Why are ground receivers all 4 channel max?

There's no such restriction.
Spektrum has a 5 channel receiver.
You can expand out a lot of Futaba receivers with S.Bus.
The bigger limit is how many channels the typical ground model needs, and how you would use those channels with the "typical" trigger and wheel transmitter layout.

I'm going to guess that the reason why receivers/radios intended for surface haven't exceeded 4 channels yet is due to there not being a need for more channels up until about now. When hobby grade surface RC's first hit the scene there were no light kits, rear wheel steer, brake/fuel mixing, etc... it was just throttle, reverse/brake (if you had an ESC), and steering and for that time period that was good enough. If people start demanding that their surface radios have more features maybe a company will listen. To me it would make complete sense to have a radio that would let you cycle through rear wheel steer options on the fly, shift, engage/disengage dig, lock/unlock diffs, turn on/off lights, am I missing anything? I can see Traxxas being the first company to tackle this, it would mean they could sell more accessories for their crawlers and such and it would give them a reason to release a new TRX-4 with a new feature, dig.
To answer the question above, I have a Sanwa MT-S that has accessory switches and the ability to set parameters for said switches, so that is one way to add the additional channels to a pistol grip radio to perform functions that I listed above, another is to add buttons (easy to turn lights on/off).

No need for not more and most of the time the needed minimized size are I think the main reasons. For the Futaba 7PX you can use an airplane receiver with 7 channels or expand through SBUS

Fly Sky aircraft Rx's are compatible with the surface based controller where Dasmikro once made a 16CH conversion, I'm sure this could be fully utilized for a battle bot, ha!
Here's a demo of the 8CH version that I bought and tested:

Real estate is hard to come by on some RC's, I personally don't see daisy chaining receivers as a solution to adding more channels. Are the surface radios that were suggested by people capable of assigning functions to those extra channels added when daisy chaining through the programming screen like the MT-S, because if that's not possible it's kind of pointless to add more channels if they cannot be individually controlled or programmed to operate as desired. I think the solution people may be looking for is 1 receiver that works with a radio that allows you to assign whatever is desired to a specified channel. Also take a look at the receiver/ESC that comes with the SCX-24, appears to be more than 4 channels.

Here's a 5 channel surface receiver made by Traxxas. This is what's included with the TRX-4. 5 Channel Receiver Traxxas states on their site that the receiver is 5 channel and A-Main states that it's 4, so does anyone with a TRX-4 care to chime in? Are all 5 channels used on a TRX-4 with multi speed gear box and diffs that lock/unlock?

Everything is programmable on the DX5 Pro I use for that (M17 for racing), steering and throttle as usual, high/low on a thumb rocker switch, 3 position dig on another thumb rocker to switch between the 3 set points of neutral and EPA each direction. Lights are set on a push button since the light controller just cycles through settings when it sees an input.
So yes, if you are using a high channel count with a suitable radio and receiver, you can use it all. You sometimes have to be creative on what button, rocker, or dial you assign to the function and take your time to set everything up so you don't burn up a servo, but that's also part of the hobby when doing some sometimes complicated setups.
