But let's first figure-out if word-only smbus are really a thing

Some grep foo on /drivers/i2c/busses might answer that.

Did that and haven't found any driver in mainline which is word-only.
All drivers with word access capability have byte access too.

So for the moment, maybe add a WARN_ON() for an I2C bus that only
supports word access, and we can deal with it only if we ever get a
report of it firing.
