Hi, Dmitri,

This is me as an individual, asking a question, and NOT making an informed
observation or suggestion ... but I was curious.

I note that TSVWG  currently has two FECFRAME docs in WGLC now:



The intent for these documents is to add support for sliding window FEC
codes to the RFC 6363 FEC Framework, which was limited to block FEC codes.

I don't know whether there is any relationship between your proposal
(moving from framing to a stream for compression) and the work currently in
TSVWG. I have some guesses, but not well-informed guesses, so thought I
should ask.
