in my understanding it is essential to have "font 16-bitness" on the
abstract level of TeX (i.e. metric features; specific glyph
representation is very much secondary), not connected to any specific
font format like Opentype.

TeX has always been independent of physical font formats, and that is
it's strength... [and omega's 16-bit fonts are no exception]

are there any preliminary considerations or descriptions of how it
will work (of course not detailed - just to understand the proposed
idea of such a replacement of OTPs)?
