Those are reasons against.

We in the technical community need to develop or modify our tools to
make those tasks easier.

Hire a lazy but smart admin! :)

actually RPF is extremely effective especially where its highly 
asymmetrical, eg at the edge. theres virtually no reason not to RPF 
dialup/isdn/cable/dsl/etc customers for example.

Sure, but to RPF so many customer facing edge ports in comparison to the
far fewer number of egress ports makes the implementation procedure
quite extensive.  The more configuration, the more room for errors or
"oops, forgot to configure that there", not to mention change
management.
