If there is a bug or feature that really matters to you and that you feel is not being prioritized:
- Contribute a fix
- Convince someone to contribute a fix
- Complain enough that someone contributes a fix (which shouldn’t work but sadly often does)
Otherwise it will be fixed when it is fixed.
(I am biased because I work with the TS team. However this is just general open source stuff, I’m not speaking professionally)
