Limitation drives innovation, I'm sure the size community will have something new in a couple weeks.
Granted before, animator scalers played nicely with avatar hiding features; I fear if a new workaround uses for example SteamVR drivers, that is not something that can be hidden.
The VRC beta broke avatar scaler addons and unfortunately they've stated they will not be fixing it, hopefully a workaround is found eventually.
Sucks for anyone who makes size content.
