No, the original metaphor is they were planning to build a nuclear reactor and they spent significantly more time than expected on the details of the bike shed because it was simple to understand and change, unlike the details of the reactor which were complex and required expertise and had lots of constraints. Who cares what color the bike shed is, we're building a nuclear reactor here!

Took me a sec, but well played

Indeed, that's the original metaphor. The thing is, we are not building a nuclear reactor here, we're building a bike transport system. :-\
