Nothing to say on my side.

Pretty unfortunate that we got issues with ZFS.
Orphans are never removed automatically by default, I doubt it will start anytime soon.
js60 does not totally replace
js52. You can have
js60 concurrently without problem (or without problem that I know of I guess). On my side, I have
polkit that now depends on
js60 instead of
js52 starting with 0.116-1.1 (the previous version depended on
js52) and I still have
cjs (package for Cinnamon) that depends on
js52. I have both
js60 installed at the same time.
