I’m an “outsider” in that I’m not involved in the development of HDF5.
I was wondering where discussions about submitted HDF5 RFCs  take place? Is it here on the forum somewhere, or elsewhere?
Is there a description of the process for RFC submission? The  page just lists the RFC PDFs, but nothing else.
I was specifically interested in whether there had been any discussion about the RFC: Multi-Thread HDF5 from a couple of years ago .
 HDF5: RFCs
@elvis.stansvik thanks for bringing up a few important topics.
I’m not aware of other venues than the weekly HDF5 Working Group meetings, but this forum is as good a place to have a more “asynchronous” discussion.
I’m afraid, there isn’t, but I agree there should be one, and I’d be happy to work with anyone interested.
Unless somebody has a better suggestion, how about creating a thread with the RFC ID/title as subject, e.g.,
[RFC THG 2021-05-28] : Multi-Thread HDF5
