Please just watch the talk by Paul Vixie (who is one of the really big DNS
gurus these days, even ISC BIND maintainer for quite some years).  And you
will see that DoH is pointless when you have DoT.  But DoT can also go much
further than DoH will, when you consider the bigger part of the DNS query chain.

Plus, ignoring the local networks DNS also has its own set of challenges when
being added directly to browsers.  Like hostnames only available inside a
local network will no longer be available.  But again, watch the talk, these
points are well covered there.
