On this topic, I note that Joao Damas and I tested the level of support for DNSSEC validation using ED25519 in May and June this year. The writeup of this measurement can be found at https://www.potaroo.net/ispcol/2021-06/eddi.html. At this stage a number of large ISPs that operate DNS services perform DNSSEC validation do not support this particular algorithm, and the level of support in DNSSEC-validators is in total some 50% of the level of support for RSA and ECDSA P-256. This may change in the future of course, but at this stage it does not appear to offer any compelling features that stand it apart from ECDSA P-256, and some significant differences in the lack of algorithm support in validating resolvers.
