Spelling of cyanobacterial names

Hello,

May I ask if the name spelling of cyanobacterial taxa in the GTDB follows the tradition of the ICNP? or ICNafp instead by means of Rule 8?

I noted that the GTDB now has Vampirovibrionia instead of Vampirovibrionophyceae corrig. This case happens to be an example newly added to the 2025 revision.

Thank you.

Best wishes,
