> It's not that those steps are necessary to prevent damage,

It is my understanding (but I'm not even remotely an expert) that e-paper panels can suffer from permanent display burn due to the charged ink particles sticking to the glass. The stock waveforms take this into account and prevent it from happening. However I'm not entirely clear on the low level details or if this only applies to some subset of panels or etc.

Yeah that was an issue with the 1st Gen of panels but that was solved over a decade ago.
