At least, I do use it. A lot. I rely on it.

I do not observe the breakage as described in the first message, mostly
because I use refile cache exclusively for org-refile. Yet, I often see
"Please regenerate the refile cache with C-0 C-c C-w" when I do a lot of
batch refiling. A faster, more reliable, caching would be certainly
welcome.

In general, various parts of Org mode code base implement different
types of caches in parallel. I am aware at least about org-element,
org-scan-tags, org-agenda, org-refile, and org-goto. Probably Org mode
could benefit from unified caching mechanism? A good implementation
coming to my mind is org-ql [1]. It implements tag caches, outline path
caches, and can even be used to cache results of an arbitrary function
with point at heading. Basically, all (except org-element) types of
caches Org mode uses now are already implemented in org-ql in unified
way.

WDYT?
