The complaint for font-lock-maximum-decoration is that it’s obscure and too 
corse-grained. So my idea is for each major mode to provide fined-grained 
controls like python-fontify-type/f-string/assignment/built-in/etc. And 
tree-sitter makes it easy to implement this kind of toggle. But I guess a 
global control is also nice, I can make tree-sitter respect 
font-lock-maximum-decoration, in addition to the fined grained local-control.

Since we are designing a new system, I don’t think we need to resort to the 
likes of font-lock-ignore.
