I did that Saptapper GSF pack a while ago (posted here IIRC). Caitsith2 seems to have lost interest (or rather, is busy with automatic song timer based on blargg's GME and/or SNSF). Unknownfile is busy with the new 2SF format (zero points for guessing which system it covers). There were a few rips done by Labmaster a while ago, but after that silence. The current rippers are more interested in other formats (Sega 32bit for kingshriek, GBS for ugetab).
I'd love to have at least rips for Manfred Linzner games, but alas, doesn't seem like it's gonna happen soon.
