Sorry, don't agree.

I'll tell you what I use. I use the gen_servers. I have never used any
of the other gen_ modules (except gen_tcp of cource ... but that
is an entirely different beast, then gen_ in gen_tcp only has the
name in common with gen_fsm and gen_event)
I actually do use applications. Not that I like them but if I want to
write an erlang program that fits into the otp tree I must do that.
I've never used the release handler, I barely understand the
error_logger. Everytime I need to do something with the error_logger such
a duplicating error_messages to go to yet another place I have to look
deep and hard at the code again.
I've never had a supervision tree deeper than 1.
