Is this zonefile legal or should it be changed?

The H/W/D/M notation is and always was illegal. Some versions of BIND8
allowed its use in zone files. BIND9 doesn't. It's also possible that
some versions of dig use this symbolic notation when presenting TTLs
and SOA values. That's harmless unless the dig output gets shoved into
a zone file.
