That seems to go against the idea of tip4commit, the idea is that contributors (through pull requests etc) can be compensated as well automatically. Same if there's multiple contributors to a project the compensation is split between them based on the amount of commits they make.

Maybe the better solution would be to look for Bitcoin wallet addresses in commit messages. If maintainers don't like it they can scrub them on merge.

Couldn't that be fixed by having contributors creating a specifically named repo with the address in a file? Still opt in. It could be opt in for the maintainer too, following jchrisa's suggestion, meaning the maintainer could veto payments.

Except everyone knows that asking for forgiveness beats asking for permission every time.
