It's notable that draft-jabley-reverse-servers intends to put

Most important TLDs are moving towards in-bailiwick targets for their
NS records and accompanying address records. Or have already done so.
One of the main reasons is to reduce latency and sysqueries. The
referral response returns all the info and the resolver doesn't need
to resolve the address of ns.whatever.othertld in order to get to the
name server(s) it next wants to query.
The root servers indirectly achieve the same result because they all
serve root-servers.net. IIRC the reasons for not putting the names of
the root servers into the root zone were down to complications in the
database/systems which were used to generate the root zone ~15 years
ago. This would have been around the time when the names of the
servers got rationalised. Making that change today would generate a
bazillion layer-9 problems. These are best avoided because a tidy-up
of root server names would get caught up in the maelstrom of new
gTLDs, IDN ccTLDs, root signing and IPv6 which is keeping everyone
more than busy.
