Yeah, releasing broken code and especially where we do not if there will be
maintainer to fix it or not seems risky for me too.

One option is to deprecate it for wallaby which means follow the deprecation steps
mentioned in project-team-guide[1]. If maintainers show up then it can be un-deprecated. 
With that, we will not have any compatible wallaby version which I think is a better
choice than releasing the broken code.

Releasing the broken code now with the hope of someone will come up and fix it with
backport makes me a little uncomfortable and if it did not get fix then we will live
with broken release forever.
