Someone with access please hit Merge on that. :-) It adds PSR-10 to the
list, and I also added Sponsors to everything based on the respective
PSR meta-documents as those were missing.
It also turns up a few gaps with shifting members that need to be
addressed. I will start new threads on that momentarily.
