Just to confirm: mintty does no such thing, and I don't know what it
could be doing. All it sees is a file descriptor for reading and
writing the pty device, so it doesn't even know what sort of process
it's talking to.

I think any solution to this issue should be done as a standalone
wrapper that needs to be invoked explicitly, at least initially. If it
proved itself, it would be worth considering to invoke it
automatically from the Cygwin DLL when a Windows program is spawned.
