> @Vipul-Cariappa Thanks for the backport. This isn't a regression (the old cleanup behavior is also in 22.x) and doesn't look critical, so I'm not sure it meets the bar for a 23.x point release. Is there a reason it needs to be in 23.x rather than 24?

tl;dr; that blocks a downstream consumer from moving to llvm23.
