Actually, they do want a frequencies that allows more cell sites, or  
at least they want one that allows them to match the cell sites to  
the demand. If you have a hundred users in a city, then a VHF  
frequency allows you cover the city with a handful of cells, or even  
a single one. If you have a million users, you need each frequency to  
be reused multiple time in the same metro area. For that, higher  
frequencies with their greater path loss are ideal.

Does APRS have a hundred users or a million in a city? Do you want  
one or two digis, or a hundred mini-digis?

As long as the APRS answer is a hundred users, 2 meters is the "best"  
answer.
