Many SP's still do this, some take it the extra mile and block anything
with things like  cpe/dsl/cable/hfc/dyn/ppp... etc 
in the hostname, we still do it, have done for over 20 years and seen no
collateral damage.

Ordinarily, I agree, but the overall security and protection of the
network must come first, the protection of teh majority must come first.
 Then there's the law, in Australia we are required as part of the
outcome of the iinet V hollywood, to block pirate sites, 99% do this by
DNS, the Federal court accepts this method, the Federal court knows it
can be avoided by most 8yos in under 10 seconds, its the sweet spot
everybody agreed to so they approved it. 

There are also other laws that require its use as well.  That said we
dont block any ports and have no intention of. 

That said, DoH is fairly pointless here because there is no requirement
to log DNS queries, most of us have far better things to do than to know
who's going where, none that I know do it, though there is a question of
Telstra mobile 

lets face it, if we really want to know whos going where, netflow tells
us a whole lot more anyway 

Kind Regards,
