I also repeatedly say adding completely new things like treesitter
is encouraged, because someone(tm) will maintain them supposedly.
Problem is tackling what's already in there, which happens almost
never compared the former.  Overhauling display is going to require
that, I'd love to see how it would go without touching the
infrastructure or without the friction I've seen with simple mention
of it before even changing code.  If someone attempts that it would
make it simpler to believe you, because I am discouraged to take
the first step.
