I'd very much agree that AUTOSEL is trying to be aggressive with it's
patch selection (it's actually sort of like a "dial" I can adjust and
now it's adjusted pretty high).

However, please don't see it as something that is forced on you; if the
maintainers disagree with patch selection please just let me know and it
will dropped. The only reason I'm being aggressive with AUTOSEL is that
I'm hopefull it will provide better experience for our users.
