The general approach looks fine, but I have some changes.

Can you give this PR a more descriptive name? Instead of explaining the problem, it should explain the solution... maybe "recover from lifetimes with default lifetimes in generic args", or something else.

Thanks, one last change then I think this is ready to approve. Maybe we could also suggest removing the default lifetime param, but I don't think it's super necessary.

I think your rebase hit the case described in https://rustc-dev-guide.rust-lang.org/git.html?highlight=rebase#git-is-trying-to-rebase-commits-i-didnt-write

This should resolve itself automatically by rebasing over the latest rust-lang/rust master commit again
