I've gone back and forth on that. The argument that may sway me is
trying to stay as close as possible to standard library containers.

I'm not sure. Some folks want the highest possible performance, don't
care about portability, and are willing to accept alignment
limitations. Many others want some combination of those. That implies
a lot of use of the Traits parameter.

But the current ordering does seem to be a bit of a lightning rod!
