When I briefly played with FF nightly and DoH, it was
using both the system resolver and CF. I had to muck
about some to get it to actually use the CF results
because of entries in the system resolver cache.

My point though was that the dichotomy in Vittorio's
draft is too simple - I'd guess its likely that a
browser, if doing DoH for real, would end up trying
various DoH servers as well as the system resolver
and would make possibly complex choices based on the
queries, answers and metadata (e.g. speed) seen. And
those choices could of course change as the browser
s/w is updated (all that being in addition to the
kind of user-driven config stuff Vittorio's draft
mentions).

Cheers,
