I think you were missing the implication of "if possible", the implication
being that the driver can now not be used in a multi-platform image, and that
having a bool driver depend on tristate drivers doesn't make much if any sense.

The argument in the exchange is odd - one can not remove any driver as long
there are client drivers / devices attached to it. This is true for all
drivers, not just for this one, and handled quite nicely by the driver core.
Just run "lsmod" and try to remove a driver with any attached users.
