Ugh. I'd been too far away from ECUSA bishops to know this, but it fits what we're seeing.
(Not clear on the pro-/anti- 1928 BCP positions of that Synod, however.)
In the late 1980's, a major point of contention was that there were still ECUSA parishes wanting to use the 1928 Prayer Book, but the practice was being ruthlessly stamped out, sort of like the Latin Mass.
That Synod (which was the first formal gathering of "traditionalist" ECUSA bishops to date with the intention of holding some sort of line), was convened with two major rallying cries: opposition to female ordination (particularly the consecration of Barbara Harris to the episcopacy), and tolerance of the "old Prayer Book."
This all seems rather quaint in retrospect, with the line in the sand now being whether open buggery should be allowed in the rectory...
