Thanks for the list Stephane. The .se zone is also freely available
since May at https://zonedata.iis.se/

I also regularly monitor the TLD space with Zonemaster, which can give
us a fresh list of TLDs with open AXFR:

Also keep in mind that most of the newgTLDs are available through the
CZDS ICANN service: https://czds.icann.org/
