I know Apache uses WINCH as well which makes me wonder if there was some historical reason a server process wound up using a signal meant for a TTY?

It's otherwise unused in the context of a daemon. SIGHUP is similarly popular and historically designed for use with a TTY.

That's what I suspected - that it would pretty much be guaranteed to not to be needed however I was not able to find any historical UNIX lore mentioning it specifically. Cheers.
