It's probably ok, however, I can think
to 2 other possible problems.
First is the "local on" sense current
from the appliance module.  It might
cause some weird effect.  Then again, it
might be enough from some
switching power supplies to keep it
idling.  Also, you could use a modified
module or one of the newer ones where
this feature can be turned off.
The 2nd problems that might happen is
unpowering the receiver for long
periods (weeks) might cause a loss of
memory, like for presets, etc.
Both depending on the receiver design.
