It's still valid -- the only reason why I'm not opposing to the removal is that I can see a *small* benefit in not leaving behind old definitions like that, which show up whenever you grep for the function name in the whole monorepo.

Basically, I don't mind whether we keep it or not. I think the benefit is small, but the loss of test coverage is also very small, since I assume those symbols were just taken more or less randomly and passed through `c++filt`.
