In reference to MqExtention, I've used Stacked Git (a git equivalent)
in the past, and would generally advise against this. I like to
commit after I get a piece of something working, so I know I can go
back to that point if I try something and it doesn't work out.
Stacked Git makes this hard. In my opinion, you're essentially
by-passing a benefit of a scm tool.
I wouldn't advise people to use MqExtension unless they understand
that if they make a mistake they must undo it manually.
