If that were my only concern, I'd focus on rate-limiting WHOIS,
and still admit reasonable requests for zone file access when
presented with evidence of a legitimate use-case.  I am guessing
there are more reasons than just that... :-(

Overall I have 1,173,206 .br domain names of which 239,412 or
20.4% return a validated answer (perhaps NODATA) for MX lookups.

Frederico reports 1,044,645/3,959,979 or 26.3% DNSSEC/TOTAL, so my
present dataset appears to under-sample the signed domains.  The
relevant suffixes are mostly:

1079739 .com.br
  21925 .org.br
  16640 .ba.gov.br
  13413 .blogspot.com.br
   9533 .net.br
   3663 .adv.br
   3063 .ind.br
   1544 .art.br
   1449 .inf.br
   1409 .edu.br
   1188 .eng.br
   1162 .br
