The upgrade cleared in the end. Here's a couple data points:
Feb 10 - ticket purchase. Put in upgrades for wife's (non-status) first and then mine (*G). Wife's waitlisted, mine cleared ahead of hers. Inventory I is showing I9 all the time.
Feb 10 to Mar 7 - Wife's still waitlisted. Inventory for I was dropping from I9 to I1. Pulled off the GPU and re-apply does not help.
Mar 7 - Wife's upgrade cleared spontaneously
My butt is saved from Y in the end
Conclusion: *G might matter in GPU clearing on LH.
