Actually, I've heard conversations of this sort many times...

engineer:  "Ok, we've got a good design for the 5V switching regulator;
it'll cost about $2 for parts."

manager:  "A switcher?  Can't we just use a regular regulator."

engineer:  "A linear regulator?  Yeah, it'll only cost about 50 cents, but
it'll get really hot..."

manager:  "But it'll work right?  Why spend the extra buck and a half?"

engineer:  "Sure, but the lifetime will be shorter and if there's any
cooling problem..."

manager:  "Fine then.  Linear regulator it is."

Sigh.
