Cycles principled shaders and glass shaders

Hi guys,

I was just wondering, i know people often use specific shaders for glass, to get results that render faster and are good enough for them. This made me wonder, would it be handt if there would be a principled glass shader as well (with the best reciepes in itself).

And also, i was thinking the principled BSDF does do people frequently at certain reciepes to it ?
I add sometimes a node reciepe to make raw materials reflect under sharp looking angles.
Now that it is available for quite a while could new insights , new reciepe inprovments be added if so what would they be, (perhaps things like anisotropic direction indicaters?) or you name it…

Anyway perhaps we could share some reciepes here and discus principled
