I'm glad that is the case! In my opinion this is the right behavior.
The new behaviour is great because it avoids modifying the subrepos
(by creating _new_ commits, often with a nonsensical commit message)
unless you explicitly tell mercurial to do so.
But changing the subrepo revision does not modify the subrepo itself.
You are basically modifying the .hgsubstate file, which is part of the
So in my opinion this makes a lot of sense.
