Re: 3d favicons

Rik,

glTF is a good format for models; however, there are several issues with 
it being using as a "favicon"
1. glTF is not necessarily a small display format and it is hard to 
automatically downsize a model. Favicons have the very nice property of 
being very small in (disk space) size. Models are not necessarily that way.
2. glTF is a transmission format, not an archive format. glTF V2 is not 
backwards compatible with glTF V1. There is no current guarantee that a 
V3 format would be backwards compatible with V2.

I don't have a suggestion for what might make a good format that is 
inherently small and long lasting. Perhaps a new concept would need to 
be developed.
