I was searching where the Savox was mentioned but I had some contact with Savox in the past and they have no servo's supporting these faster response signals. The 1257TG just use the normal 1-2 msec signal and will not react to Futaba its 760 usec and Sanwa its 300 usec pulse. And no way you can make that work unless you hack the servo its firmware (beside the question if the processor is fast enough to work on those higher speeds)

Anyway, I can feel what I feel regardless of what you believe.
And like I said, other top of the line radios and servos offer pwm frequencies significantly higher than 400hz, so elrs can't claim to be a totl system of it can't offer the same features. The devs are too ignorant of the surface market know elrs is deficient in that regard, and because they clearly have the same attitude as you, they will undoubtedly stay ignorant of it's shortcomings.
Of course you can provide a signal of 0.5 to 1 msec because most normal servos can handel a pulse in the range of 0.5 up to 2.5 msec but your servo will have a limited move as well if you try to limit it to 1 msec.
