Are you certain that nothing will break or no plugin will be
constrained by that? If not, we should consider it for rebar 2.x as
well.

Well, it depends on what response times your other interactions with
the machine in front of you have. Icon animations and other solutions
were implemented to signal that it's pointless to click again and one
has to wait for the action to be completed.

On the command line it _definitely_ has to be under .5 or .4 seconds
to not disrupt, so going from .6 to .3 is very noticeable difference.
