Seems like Pleroma had it working before mid-2020;

pleroma.social/announcements/2

The Epicyon server has support for AP C2S too, so that could also be used to test apps trying to implement it;

libreserver.org/epicyon/

Was any of this mentioned in the SH thread?

@strypey @smallcircles @skyfaller @hugh @bobhttps://rdf-pub.org is providing c2s. I started Testung with #andstatus but there where open questions regarding oauth if i remember right.

Also #SocialHub#ActivityPub developer forum has a bunch of C2S-related topic. You can use the forum search facility.

A very detailed investigation on what is needed client-side can be found in the #AndStatus project. It was never completed AFAIK as there were among others no server implementations to test against.
