I've watched this thread, and I happen to notice today a listing for a set of trunk bins from Teslarati. They let you select California or Texas build as product options when you order:
Teslarati MY Trunk Storage Bins
It's not clear exactly when the Texas version will ship; the description says "Trunk bins for 5-Seat Texas-built Model Y available in December 2022". It does appear you can place the order now on alsomewhat of a Black Friday sale. I haven't tried because I have a 2021 and already have the Tesla OEM bins.
I'm sure this means that other suppliers will be coming along shortly, but someone who could use them might want to get in early and report back how well they fit.
