That's exactly the point.

Hams should also know CW at 20 WPM.

Or at least to know 5 W.P.M.   :-)

That's far more useful, interesting and productive activies involving
APRS then spending hours and hours tweaking paths and beacon rates.

When I send Email or load a web page on the Internet, I don't care what my
IP number is, the IP number of the destination, the time to live and the hop counts.
All that info is there if I want to dig, but for general day to day operation, it's
not needed.  I give it the name and the system does the magic for me.

Trivial with a smart digipeater like Digi_ned.   The folks configuring the
network have complete control of what it does.
