Heya, thanks for your feedback. I agree as well!

But while it's trivial to make notmuch-mutt itself support
$XDG_CACHE_HOME, it is less so for the Mutt configuration snippet
(i.e. the notmuch-mutt.rc file which is part of my submission). AFAICT
the <change-folder-readonly> function does not support variable
expansions, not to mention default values while doing so. As a result, I
can easily support $XDG_CACHE_HOME for, say, the history file, but I
don't know how to make mutt look in some $XDG_CACHE_HOME derived
directory. (Yes, I'm excluding hackish solutions like have mutt look
always in the same dir, and make that dir a "moving" symlink that will
be changed by notmuch-mutt upon execution. That seems to defeat the
benefits of the XDG specification, at least partly.)

Bottom line: I'll be happy to properly support $XDG_CACHE_HOME, but I'm
in need on suggestions of how to do so for the Mutt configuration part.

My thought exactly.

The proposal of documenting how people should use ~/.cache/notmuch is
great, but I was hoping it can be overlooked for contrib stuff that has
been vetted by you folks.

Thanks for your help (and for notmuch!)
Cheers.
