They are not a fireable offense in my book either, but they sure as hell wouldn't pass my code review. I've had to deal with too much crap like this in the past. Self-proclaimed senior devs that micro-optimize everything and leave a mess, then leave. Love them.

One should always optimize for easy maintenance. Performance is always a secondary goal, because it doesn't matter how fast (you think) your code is if you can't understand it.
