The phrase alternate sysres is a part of my culture, or at least was

You don't mention whether you have MIM available to span ENQs across your
plexes, so I'll presume that you don't. If that is correct, then you
should NOT share a sysres across plexes since you will not have data set
integrity from one plex to the next.
Not true. Old GRS Ring mode (CTCs)

You can't with GRS; you can with MIM (as long as its control file is not in a

Maybe so, but several posts said that GRS can't do it, not doesn't do
it well. For years, GRS ring was the only option, yet a lot
