Following up on what I posted earlier, I was able to confirm that the OSSC successfully handles 480i RGBS via AV3 in most cases. Tested PS1, Saturn, PS2, and Wii. For some systems I needed the interlace hack in the compatibility settings. What did not work at all was 480i RGBHV from a Dreamcast.
And man, now I can see why that LPF is sorely missed on AV3. It's noise city with pretty much every type of signal I checked, except the Wii (with WiiDual), that looked very clean. If I stick with this setup it looks like I'd definitely need a DE-15 to SCART cable, or I guess a DE-15 to RGB RCA cable for AV2? I'd prefer the latter as I hate SCART connectors.
If you're mainly handling RGBS (as suggested by the majority consoles you mentioned having tested), I would go into AV1 with a DE-15 to SCART adapter/cable; same LPF support as AV2, and it'll be simpler to set up, because you don't need to strip sync from any sync-on-composite or sync-on-luma sources.
If you were to go into AV2, I expect you'd need to 1) strip sync from those sources (because RGB interfaces generally ignore anything except clean composite sync), and then b) run them into something like an Extron RGB interface to rewrite RGBS to RGsB in order to get it into AV2.
Sadly, I don't think the community really has an alternative to Extron's RGB interfaces; I think it would be really nice if the community had something like that that could, notably, accept CVBS and luma as valid sync signals, and could auto-detect any kind of sync signal (including handling both 75Ohm and TTL) and strip/mux sync into whatever anyone needs. Bonus if it could auto-detect YPbPr as well and/or do colorspace conversion with both RGB and YPbPr outputs. The closest thing we could get to that would probably be a secondary, upstream OSSC with everything set to passthrough, paired with either an HDMI-to-YPbPr or HDMI-to-VGA converter, and then LPFs turned off on the downstream OSSC. :/
