It may be ok to just keep that in wined3d_state. I'm not sure
wined3d_device_set_texture_stage_state() would really need to touch it
though. While you could in theory avoid submitting state changes above
lowest_disabled_stage through the CS, I'm not sure it would really
gain you anything, and it could very well be more complicated than
just submitting those, and only using lowest_disabled_stage on the CS
side to avoid dirtifying states.
