Re: [PATCH v2 2/2] t/t3308-notes-merge.sh: succeed with relaxed notes refs

Johan Herland [off-list ref] writes:

Alternatively (or additionally), for issue (2), we could add a
--disable-ref-safety option to 'git notes', to explicitly disable the
safety checks for "experimental" use.

I actually would rather prefer to see a proper plumbing use
supported, either by a new "git notes-plumb" subcommand or "git
notes --<some option>" that gives the scriptors a stable interface
to the low-level machinery without enforcing any Policy that belongs
to the Porcelain layer.  At the very least, the plumbing should:

 - disable anything that introduces potential ambiguity, e.g. DWIMs
   done by expand_notes_ref(), but not limited to it.

 - lift any restrictions based on policy, e.g. "where can notes
   trees live" (again, but not limited to this).
