However, there are a "scad" (to avoid having to say either "many" or
"most")
of AMs that do not deserve to exist, as they cover very little, or have
miserable facilities and high-Q DAs and no intent to improve. I just
wonder
if IBOC may create a band cleansing in the process.

Could you clarify a portion of your statement for me? Are you really
saying that AM stations with little coverage should just go dark?
What about AMs that serve small towns and rural areas?

There are many stations in metro areas that have signals that are so
directional they cover only one side of some streets! Often, these don't
cover any cohesive area, and are simply inadequate for any purpose.

Other stations are so limited in power, or so directional at night they
serve no useful purpose.

Stations with low power can serve small communities. But defective signals
in metro areas are generally not doing anyone any good.

Cleaning out the band selectively might enable some rural stations to g
fulltime usefully, or some metro signals to cover the entire market by
losening the protection requirementos .

Just wondering...
