I ran into a related issue recently too, and it appears indeed that the
problem is widespread.  See:

https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/327362

At least the following ISPs appears to serve .local zones (although not
necessarily with A records) to their customers:

TeliaSonera (Nordic)
Bredbandsbolaget (Sweden)
True Internet (Thailand)
M1 Home Broadband (Singapore)
Golden Telecom (Russia)
Beeline (Russia)
Corbina (Russia)
New Orleans city wifi

Mac OS X appears to filter out all .local data received via DNS from the
net, see the end of:

https://support.apple.com/kb/TA20999?viewlocale=en_US

Given the widespread damage, I have sympathy for that approach.

Btw, I don't see the note about .local in RFC 6265?
