There is quite broad registrar support, some of the original people behind it at GoDaddy left for other projects and so I think the team have got some things to tidy up. It's been around much longer than a year though.

> IONOS, one of the providers, only lists four companies supporting this standard as a whole, DNS or service provider

The way Domain Connect works is that the registrars have to "onboard" templates for each service provider that wants to use the protocol. So the registrars get to choose whose templates they want to use. So this could just be a list of the providers IONOS have onboarded.

A company doing interesting things with Domain Connect and in this space more broadly is worth a mention: Entri [1]
