This is a separate item from the ANPRM withdrawal re transponders in gliders.

§91.225
Automatic Dependent Surveillance-Broadcast (ADS-B) Out equipment and use.

In typical governmentese, that reads like a plate of spaghetti. I
understood that to mean that gliders are exempt from having ADS-B Out
installed. I will still pursue and installation for my ship, however.

I am not following, Is there a question or point you are making here?

Nothing has changed related to this regulation in a long time and this has all been discussed on DUC many times. The significant change to 14 CFR 91.225 back in early 2015 was the adoption of "meets requirements of" wording which allows experimental aircraft to meet requirements of 14 CFR 91.225 by using non-TSO but "meets requirements of TSO..." devices for ADS-B Out. (and that change was less intersting for experimental gliders than other experimental aircraft because of their overriding exemption).

Thanks for the link, I know the person that asked the question.
