The flag is here, but very few modules use it for instance. This is
deliberate as it's a feature in test stage and as I don't wanted to be to
restrictive for instance. IIRC the flag is added to demosaic, clipping,
colour in and out.

fields : multi_priority and multi_name. Styles, as history stack use module
op name (as before) AND multi_priority to differentiate modules. For
presets, multi_priority is saved but ignored at applying step, so any
preset can be applied to any instance.
