Right. What could and IMO should be done (ie, I do it when I'm RM :-)
is to tag the branch point. That is the last "known good" point on
the trunk (given the Emacs release process).

Why? You're doing essentially the same thing anyway if you check out
a tag. It's not a branch switch, but you've got the wrong code base
for making changes to. ("Wrong" in the sense that you run a risk of
unnecessary conflicts when merging your changes.)
I'll grant that the bzr implementation of this gives me hives, but
from the user point of view a shared repo (efficient storage of
revisions common to the branches of interest) plus a lightweight
checkout gives you the same effect as colocated branches for this
purpose, at the slight cost of setting up a shared repo and learning
an extra command IIRC.

No, you can't, if "known good revision" is what you want. Any
instability introduced *in the trunk* since emacs-24.2 branched from
the trunk is still in the trunk. You do not get a "known good"
revision. You only get fixes to emacs-24.2 since the branch, but
these should be pretty small, and won't address "new" instability.
