I might well be one of those people, though I might not use quite all those options.

Doesn't have to be just the "boss" fights, though; the same idea could be applied to any fight where you know going in that it has to be a set piece e.g. the monster is trapped where it is and can only function once the PCs release it and the PCs can only release it in a particular way.
Problem is, adventure designers will insist on applying these ideas to fights that aren't necessarily set pieces; those where both the PCs and enemy's actions can easily dictate a much different encounter each time it gets played, but the adventure author assumes the PCs will always do x and the monsters will always do y. (most of the 4e adventures I've read and-or run are bad for this; some 1e ones are also)
But yes, an encounters book like you suggest would be useful for inspiration, if nothing else.
