Well, it won't work any better, just as well as.

Well, Outlook didn't used to be able to connect to Gmail IMAP in our Mac product and now it does.

That's not true. First, if there are bugs that affect our products, it will likely affect both our Linux and Mac products, and we'd fix it in both.
But more to the point, as I've said before, the schan_imp_* stuff is a very, very thin wrapper around the platform library (Secure Transport on the Mac and GnuTLS elsewhere). It is quite unlikely that the sorts of bugs you're concerned about -- in the logic of schannel -- would be in the platform-specific code. They'd be in the code that's shared. So, the fixes would be shared, too.

Everybody, whether volunteer or commercial, devotes development time to Wine to "scratch their itch", however they define that. For us, it's largely to meet customer needs. This work did that. The work you describe doesn't, particularly. It may, someday. It is quite a bit more likely to now because our Mac product has schannel support, so it will get exercised by many more of our customers, and they'll find the problems with it. (Or, if few real-world applications encounter limitations with schannel as it stands, then schannel is de facto fine as-is.)
Lots of work contributed to Wine doesn't benefit everybody, but only improves things for one particular use case. It's still an improvement to the project as a whole, even if most don't receive the benefit.
