The suggested change from the email landed in systemd-resolved 253
(Mantic): https://launchpad.net/ubuntu/+source/systemd/253.5-1ubuntu1

So it's easier to adopt Netplan's configuration using systemd override
configs, e.g.:

$ cat /etc/systemd/network/10-netplan-eth0.network.d/override.conf 
[Network]
MulticastDNS=resolve

For all common usecases, it's suggested to use Avahi instead of
Netplan/systemd-resolved, to manage the mDNS needs.

Title:
  Missing support of mDNS

Status in netplan:
  Won't Fix
Status in netplan.io package in Ubuntu:
  Won't Fix

Bug description:
  Version: 0.97-0ubuntu1~18.04.1 and 0.97-0ubuntu1~19.04.1

  Resolving .local addresses with mDNS (MulticastDNS) is supported by
  resolved / networkd while netplan doesn't allow to configure this (or
  it isn't documented, which would be equally bad...).

  Therefore please include mDNS capabilities!

  Enabling mDNS should require enabling it globally(/etc/systemd/resolve.conf)
  MulticastDNS=no/yes/resolve

  and additional per device in the device specific .network file:
  [Network]
  MulticastDNS=true/false/resolve
