IMHO good move for the ecosystem overall.

Beyond that, the formulation is really funny (bad?) though:

> Trading will move into limit only starting December 28, 2020 at 2:30 PM PST, and will be fully suspended on Tuesday, January 19, 2021 at 10 a.m. Pacific Standard Time

Assuming limit only == post only orders (which sounds like it in the sentence), how do you expect the trading to work?
