Why? The whole reason terminal emulators allow the colors to be
reassigned is so users can pick the shades of colors that they like.
If a user assigns completely different colors from the standard palette
(which should be uncommon[1]), that's their choice. Probably they are
aping a particular look, but perhaps it might be helpful to avoid
certain combinations due to colorblindness.

the vast majority of them do follow the same progression of colors.
There's no reason to assign colors to slots completely randomly.
