Very possible.  My Black & Decker MM-450 corded push mower uses a brushed

motor and a bridge rectifier.  I think one reason is that it allows them to
short the armature when it's shut off - the resultant plug braking means
that it stops RIGHT NOW.

Minor nit, that wouldn't be plugging. You actually drive the motor in reverse to plug. I might hesitate to call it regenerative braking since you don't actually regenerate into any storage. Maybe generative braking?
