Hmmm. Dependency cleaning seems like part of package removal, so it 
makes sense to do it there.

I can imagine PMs making errors in finding "unneeded" packages. OTOH, 
I'm unsure PK's target audience would understand enough to know an error 
was made, and I'm unsure it's PK's problem to deal with PM bugs.

I like event-based actions more than time-based ones, which feel 
arbitrary.
