So do you think it is a TeXLive bug?
I don't believe so.
My (shallow) understanding of TEXMFCACHE is written in the comment just
before the definition:
% First writable tree here is used by Lua(La)TeX for the font cache.
TEXMFCACHE = $TEXMFSYSVAR;$TEXMFVAR
Therefore it is intentional that there is more than one tree. I do not
know the details of what luaotfload is doing (differently), or what it
should do (differently). I hope Philipp and the other maintainers can
figure it out in response to your bug report there. Thank you for
submitting the report there.
If $TEXMFSYSVAR was removed from the list, that would eliminate the
possibility of a system-wide fontcache for lua(la)tex fonts. That
doesn't especially make sense to me.
