Very relevant point!

Which is annoying, as the /opt Requirements section even makes
provision for directories they can search:

(along with /etc/opt and /var/opt).

*/share would appear to be one of the directories the current fhs
doesn't even mention for /opt unfortunately.

Its partly defined - I guess we can either leave it optional but
add /opt/share (and whatever else is needed) as locations things can
link into, or we can require those directories be created by
distributors and used by packages in /opt. (Perhaps a happy middle
ground?)
