The bike shedding is optional once one accepts that code written by someone else might look a bit different from ones own. _Some_ conventions are beneficial, and one might discuss those, but one does not have to have complete uniformity.

Bike shedding for weeks might happen and is not helpful. On the other side of this argument there are not-so-very-pleasant things as well. A: We follow this-and-this coding convention and we do not like wasting time on discussing it so we follow it to the letter. B: I don't like this small thing that I would like to write differently. A: We follow this-and-this coding convention and we do not like wasting time on discussing it so we follow it to the letter. B: You actually don't follow this-and-this coding convention because you are not following this-and-that rule. A: Yes, that is a change that I liked.

One can easily end up with a very old coding convention that only the oldest developer likes so the oldest developer can now be dictator over everybody else.
