Yes, just a matter of usability. Different slider, different behaviour. People are use to "standard" ways, but at the end you have access to exactly the same data and you should be able to achieve 100% same results.
ProResRAW SDK allows you to access pure RAW data (just after decoding). You don't even ave to rely on debayering provided by SDK ( eg. Resolve could use own debayering engine for any ProResRAW file). If you have access to RAW pixels you have EVERYTHING you could ever have ( you just need metadata as well). Plain simple.
Every camera manufacture which allows RAW over HDMI should provide rich metadata as well. Then every tool need to be able to properly interpret all this info for every camera. This basically means it's not anymore as easy as few tabs of RAW settings like we have now in Resolve (as we have just few RAW formats tight to specific cameras). Other solution is somehow to "normalise" ProResRAW files from different cameras and present single RAW tab for all ProResRAW videos. It's all start to be bit more complicated as we are trying to use single RAW format for different manufactures. It's all still to come (if ever).
ProResRAW is nothing different than RED RAW or BRAW (well BRAW is bit covered up RAW, but this is also not really important). SDK allows for "quick" access to final debayered image (like in BRAW). You can do much more as well though, by using SDK just to decode RAW data from ProRes to uncompressed and then apply your own RAW processing. This is what Resolve can do for ARRI for example. It either uses ARRI SDK (so their debayering etc) or takes pure RAW and applies own math on top of it. Exactly the same can be done with ProResRAW (or any other RAW format which exposes pure RAW pixels). This cannot be done for RED for example as RED files are encrypted. RED SDK is the only way to get video out of their files, so you have to rely on it. Until RED did not introduce new SDK with good GPU acceleration there was nothing you could by yourself do to speed it up. It's good (as end results are repeatable regardless of the app), but also annoying as you can't take full control and introduce own processing.
All those youtubers' videos saying ProResRAW is not a RAW format as it doesn't allow white balance, ISO etc setting is very poor simplification of reality. They just can't be bothered to validate ( get to the bottom) what info they provide. Always treat those with huge distance. It's shocking how many video/processing experts we have now
