I'm not using named branches myself, but I agree that having two ways to
"kill" a branch is bad.

As I understand it, people disliked having to merge a branch with
another branch in order to get rid of it in 'hg branches --active',
i.e., to make it inactive. So I don't think they would like having to do
a merge to close a branch.
But perhaps people didn't like the merge because you had to do it as
hg update -C default
HGMERGE=internal:local hg merge foo
(or something like that) in order to make a branch 'foo' inactive. If it
had instead been
hg update -C default
hg branch --make-inactive foo
with an automatic commit as for 'hg tag', then people might have felt
different. Looking at their repository graph, I hope they would think
"okay, my branch is now superseded by 'default', fair enough."
The --active flag should then of course also be default for 'hg
