Fuji Provia/Standard v2 profile missing for X-T4 raw files

I can't speak for Adobe because I don't work for them. But on the main page for this forum there is a link to the forum where the developers monitor more closely. If you really want to know you can click on that link and ask your question there. This forum is mainly answered by other users like yourself.

You also need to consider that that V2 profile was for the previous model. And just because that profile was there for that model doesn't mandate that it will be there for a new model. Anyway, if you feel that it is that critical that you know, ask your question on the other forum.

V2 profiles are often offered to make corrections. It is possible that those corrections were included in the first iteration for the new model, and therefore a V2 profile isn't required. Is there something wrong with the profile that you have?
