I wouldn't worry too much about bending the chassis for the time being. The MTC-3 has only been on the market for a month and caster pointers and springs etc are not even really available on the market yet.
All I have read now are descriptions of bent chassis due to serious accidents (frontal or at high speed).
I have also seen normal 2mm carbon and aluminum chassis bolts stripped or bent. And that with impacts that didn't look bad. You often cannot visually assess the force of an accident (direction etc.)
The plates on the chassis (A2173F & A2173R) that lie under the wishbones probably have the exact purpose of preventing this. They distribute the load of an impact over 2 bolt holes instead of just one.
It should be no problem for third party suppliers to simply produce a 2mm thick carbon/aluminium chassis. Then you can also remove these connecting plates. Motor mount, bulkheads and even the servo mount are pinned anyway. It's not a problem than can't be solved pretty easily.

I'm not worried about the stock chassis. We just got our kits in this week and I'm starting to build one for myself. The chassis has some decent amount of flex in it, just make sure you don't forget to install the top deck screws when making changes. I did that at 180 Raceway last year with my MTC2R FWD and it wasn't pretty when I slammed the wall at the end of the straight going into the sweeper...LOL
But Ive done it with my AMX before and no its not a good thing!!

Just my theory, since the active is recommended in the rear, I think it helps artificially reduce rebound dampening and keep the tire in contact with the ground.
I could be way off base though. Interested in hearing what it actually does.

It's an interesting tuning option, though it sometimes makes me think manufacturers are just going too far. ha. But for now, let's assume this feature can help us drop tenths.
I agree with your theory, Antimullet. The shock has been shortened, but we have the potential for greater suspension travel, however floppy.
I initially set the mtc3 up with the box asphalt configuration and given the ride height (shock collar) and down stop settings, i didn't see room enough for the active suspension to even kick in--the shock presses the upper mount against the bulkhead (ie, the fixed position), and the downstop setting would prevent the arm from moving low enough to allow the upper mount to move.
So, I have some experimentation to do here just to see how to get this thing to kick in.

Ive always thought of it as a way to allow the inside tire to Droop faster, keeping in contact with the surface.
Your not waiting for the piston to travel to shock oil.
My only concern/question was how does it feel or react when the corner drops back onto it.
Probably something the bigger tracks benefit from but smaller more technical tracks probably dont use much.

The active shock towers have been around a while. Makes the car more driveable by helping keep the inside rear tire maintain more contact with the ground during a high frequency event, like curbing or bumps. I've seen cars run it in the front very infrequently. Most if not all drivers use it in the rear. You don't really sacrifice your normal setup or balance but improves stability. You just have to know what you want to do and how to properly set up your droop because now it decouples shock length from your droop limiter.
