In that thread there is a proposal for removing the old fbdev/mxsfb

That would break old DTBs, isn't this generally considered bad? Also,
are we sure the removal of fbdev/mxsfb wouldn't lose any features?

Yes, I also think we should not break old dtb's.

What my series does is make both drivers work with the same kernel
image and turns the choice into a board-level dtb decision. Supporting
everything at once seems desirable to me and it allows for a very
smooth upgrade path.

The old driver could be removed later, after all users are converted.

Agreed.

Maybe the mxs fbdev driver needs to warn users saying that that the
driver is deprecated and the bindings need to be updated to the DRM
bindings style.
