I wouldn't have much of a problem with this.
It is part of the configuration for device/driver support, and - with
the notable exception of device support that uses the extended DSET - V3
device support usually does not allow. i.e. ignores configuration
changes at run time.
The similar fields SHFT, NOBT, and OUT/INP can also be changed at
run-time, so making MASK one more with that semantics seems ok to me.
