If this is a "critical setup", then you should have a test environment
replicating your setup, to do any experimentation before deploying changes on
live system.
That's the basics of "critical environment" handling.

Nobody know, unless someone try it.
This list only providing support for current packages.
We'll do our best to help you resolve any issues that might arise from
upgrade, but it's unlikely anyone would see into any issues coming from
obsolete installs.

Fail logic. Worse, it's presumptuous. The gain is rather obvious: better

I.e., for Cygwin itself - lots of fork-related fixes for the past year.
There's also many other packages, which have been fixed/upgraded for similar

To the more technical of your questions: yes, largely.
