It seems that these comments are resolved https://github.com/vectordotdev/vector/pull/21290#discussion_r1759726163 but I dont see any documentation about this new option.

Shouldn't that be included in this PR? @pront

When this PR will merge @pront?

It looks like there were cue formatting issues blocking merge as the failed CI check shows. I formatted and pushed though so I think this should merge soon if there are no other failing checks.
