why though? number of maintainers is a function of how much work is needed now rather than how important the project is ? I would imagine sudo isn't getting that much commits/changes now. What would 10 maintainers do on sudo ?
All the other things you mentioned are just things you personally wish for but may very well be undesirable to the project.
That would be a valid point of you actually said it would be and why, not that it may be. It may also be desirable. Now what? Would the project benefit from more maintainers because there may be desirable improvements or would it not because nothing may be desirable, it's literally fully secure and feature complete?
Well, if other projects with a glut of devs are a sign, probably integrate AI into it somehow
