You say "should" be owned? Why? You're proposing a change at the SOL_SOCKET level, which means it will apply to Unix-domain sockets. What are the impacts of changing the owner of that socket to the uid of forked process, instead of the uid of the creator (presumably root)?

Deploying the proposed change everywhere that runs -current, without testing and experience, seems... premature. It has security implications. So until that experience is gained, I suggest making the feature 'opt-in', both system-wide, and per socket -- that is, the original creator has to issue a setsockopt() to enable the feature when (at minimum) the global setting is "off".

But hey, it's not my say.
