Keeping varroa under control is only a tiny part of the problem, and 
changing combs is not always necessary, except where combs have become 
contaminated due to disease, age or pesticide applications.

Keeping varroa under control is easily accomplished *many* different ways.

The real problem is keeping varroa under control while making a living 
producing commercial amounts of honey, pollinating crops and operating in 
many diverse areas where other beekeepers--possibly with other agendas and 
schedules--are keeping bees as well.

The demands of commercial beekeeping are very different from those on 
hobbyists and those who make their money in other ways than soley from 
beekeeping.  These demands may conflict with varroa control requirements and 
result in tough, even impossible, choices.

> away from the upsizing of the past 100 years.

We have been over this and over this.  There has been *no* universal 
upsizing of bees in the Americas.

> It would also help with contamination problems

Agreed.  Changing combs and eliminating old wax is advisable in cases where 
pesticides have been used in hives.

Not sure what ' not accepted feeds ' means, so cannot comment
