If that's the means that clients receive the root nameserver's public keys, yes.

That's not to say that's the only way clients could receive the root
server keys.  E.g., they could be published as a TXT record in the
root zone file.

(Resolvers will of course still need some way to securely bootstrap
this process, whether by sending an initial DNSCurve priming query, or
DNSSEC verifying the TXT record, or extracting it from the PGP signed
root zone file.)

In my experience, resource strapped DNS recursive resolvers are merely
forwarders, and therefore have no use for maintaining DNSCurve trust
anchors anyway.  For other setups, I think the cost of occasionally
downloading a file via HTTP and doing a quick signature verification
is perfectly reasonable.
