Even Microsoft has disabled resolution over LLMNR protocol in their
Windows 10. I have found that when testing something and wondered, why
mDNS works but LLMNR does not on Windows machine in our network. Found
mDNS is now preferred and updated systems get it disabled.

Found an article about that is by design, not conincidental:
https://techcommunity.microsoft.com/t5/networking-blog/aligning-on-mdns-ramping-down-netbios-name-resolution-and-llmnr/ba-p/3290816

Because the way systemd-resolved is breaking some operations in DNS, I
would like it disabled by default. Multicast DNS is preferred solution
and has separate .local domain. It makes it easier to decide which
queries should be directed to multicast resolution. Legacy users on
Windows 7 should be forced to enable it, if they want to use it.
