[avahi] Is it time to drop .local SOA heuristic?

It is required (MUST). The optional thing the RFC states after this requirement:

   Implementers MAY choose to look up such names concurrently via other
   mechanisms (e.g., Unicast DNS) and coalesce the results in some
   fashion.  

This is why I asked about whether a parallel lookup is possible; which would be according to the standard and would work for the particular use case of networks that have ".local" in use for unicast DNS.
Unfortunately that doesn't work with nsswitch, if I understand Petr correctly.

Isn't that what the RFC 6762 recommends?

https://www.ietf.org/rfc/rfc6762.txt

 Any DNS query for a name ending with ".local." MUST be sent to the
   mDNS IPv4 link-local multicast address 224.0.0.251 (or its IPv6
   equivalent FF02::FB).  


Hoping not to misunderstand something and that it helps,
