Whether they do or not, font-lock widens by default, see font-lock-dont-widen.
And even if one sets font-lock-dont-widen to nil, mode authors are completely free to ignore that setting (assuming they're aware it exists).
If we're able to demonstrate that the remaining bottlenecks are inside font-lock, it should be easier to improve there.
It has been demonstrated, as far as I can see, and repeatedly so.
