I agree; this behavior of worktree is frustrating.  It's a very common
use-case to aid in code reviews etc. and it's not easy to explain to
people what they need to do to make this work.

I think this is a very good thing about worktrees as opposed to
workdirs.

In a situation where I may want multiple worktrees pointing to the same
commit I just check out the SHA rather than the branch: you can have as
many branches set to the same SHA (detached HEAD) as you like, and
there's no concern about dirty workspaces.  This latter can actually be
a really big problem (suppose the workdir contained some modified files
then you update another workdir with the same branch... it's not easy to
figure out what happened here!)
