I'd appreciate if us Phab admins would not enable more random $stuff (Phab applications) while the number of admins who can fix followup issues with (or answer support questions about) $stuff remains the same.
Similar to "Why not enable Conpherence", "Why not enable Calendar", etc, we originally declined Slowvote in T89906.
I cannot find a trace of a discussion why and how it still got enabled at some point. :(
The (valid) questions "How can I vote?" in T220719, plus no [discoverable] docs who can vote or why not, (plus whatever next migration from Phab to something, after Bugzilla to Phab in 2014, may come up, with people asking for feature parity of all those random Phab apps stuff) are examples why enabling more stuff, plus not always documenting it, is really not that great in the long run.
