It strikes me that, if a decision can be bikeshedded to death, it's not, generally speaking, an important decision.

Well calling something a bikeshed is implicitly claiming that it's not so important. Often the specific choice is not very important, but making a choice rather than not making one is important. And while an effective organisation would not allow important decisionmaking to get derailed, many organisations are ineffective.
