Is 'Substrate Materials' safe for production?

Hi, I would like to use “Substrate Materials” for one of my assets and wanted to ask if “Substrate Materials” can be safely used for production?

I would say ‘No’ its still marked as a BETA feature as such i would not be happy to use it in a production environment. My testing of it has revealed some bugs already which might hamper production down the lines… its more ‘experimental phase’.
