It would be good to have the ability to save the Film Sim image and RAW image, like Fuji and Ricoh do.

Yes! 👆

Sony also does this – settings are only applied to lossy compression (JPG or HEIC), but RAW is saved nevertheless if you have chosen “RAW+JPG”. This comes in handy as a reminder if you, at the time of taking the photo, had an idea of where you plan to go with it but want the added headroom that comes with RAW.
