I think this makes sense when multiple permission requests are triggered by
the same user action. So I think your current approach is fine, assuming it
does what ekr said in
https://bugzilla.mozilla.org/show_bug.cgi?id=853356#c55. I don't see any
real downside.
That is not the same as what I think Doug meant in
https://bugzilla.mozilla.org/show_bug.cgi?id=853356#c53, when he said "I
tend to think we need a app facing permission request API that allows the
developer to pre-grant permissions. They could ask for the set of all
things they might be interested in (geo, camera, mic, ect.) in one API
call." Speculatively requesting unrelated permissions in advance of user
actions has some real downsides and I'm much more skeptical of it.
Thanks,
Rob
