So I guess a modulino written in Moo is triple evil? xD

It's a handy tool on the way to full modularization. There's nothing gimmicky about it unless you consider 5% of the work and 95% of the benefit of full modularization a con.

In a legacy environment, this can mean the difference between $20,000 worth of new hardware versus about 1 hour of developer time. I've scene both scenarios play out, with the former still required quite a bit of refactor.
