Unbound is designed to do one thing and do it right. To be used
on client as default local resolver it needs something to configure
it ~ dnssec-trigger. (e.g. dnsmasq is directly configured by NM)

Unbound + dnssec-trigger + NM works just fine. Also with split DNS
configuration. I use it every day at home, at work, with VPN. It
works.

I'm not saying there are any use-cases where it breaks, but those need
to be identified and solved. Writing non-technical complains with
zero information for developer in it will get us nowhere.

People want to use unbound, because it does DNSSEC validation.
dnsmasq had no DNSSEC implementation at the time there was already
unbound and dnssec-trigger.

If you use any resolver without DNSSEC the overall situation is
a lot simpler. DNSSEC simply does not work with all the hacks
people were doing with DNS before.

As for unbound vs. dnsmasq... unbound does one thing - DNS validating
resolver. While dnsmasq does almost everything (DNS resolver, validating
resolver, DNS authoritative server, DHCPv4/DHCPv6 server, TFTP server)
and has tons of hackish options. From this point of view, the choice
is pretty clear I think.
