Can you be more precise about what "support" means?

    - Support publishing algorithm 15 DS records?
    - Support signing managed zones via algorithm 15?
    - Support CDS / CDNSKEY for algorithm 15?
    - The desired TLD (registry) may also play a role...

Below is are counts (lower bounds, given incomplete data) of domains
with at least one algorithm 15 DS RR in TLDs with at least 3 such
domains in my dataset (which contains barely over 400 domains with
algorithm 15 DS, the algorithm is NOT yet in wide use):

Looking at SOA rname and mname frequencies, I see (a few providers, but
likely mostly hobbyist domains):
