Hi @Leostayner - sorry to chase you up, just wanted to ask whether you're still working on this PR :)

@MarcoGorelli - given the silence, I think you're okay to finish this up if you want.

[MarcoGorelli]

Sure. Looks like it's gone stale, so I've taken it forward in #31071 (note to OP: you're welcome to reopen this if you want to keep working on it)
