Cute Bifrost USD trick

So, recently I did some research on Maya Bifrost USD nodes and was scouting online resources a lot trying to find bits of information.
And somehow I found absolutely brilliant Bifrost discord server and one guy offered very elegant solution for Maya USD: small Bifrost network that allows you to switch between USD Cache and Maya Reference right from the outliner, using USD Variants.

At the end of discussion Guillaume Laforge shows on how to implement this in Bifrost.

And I decided to create a small proof of concept compound to load any USD/Maya Reference into the Stage with one Bifrost compound, into any custom path.

Here we go:

I need to check if it’s possible to cache from the same menu, then it could be a really cool USD workflow where you can correct things in Maya ref and quickly cache stuff right away, without any additional tools, just with a compound.

Image: if you right-click your USD tree in outliner, you can see there’s 2 Variant Sets, and more representations could be added, like proxy.
