It seems that way to you. More study can reveal how those
distribution voltages are related. You may bother or not.

I know exactly how they are related, (I some how doubt that you do
given the phrasing in your post) and I know exactly who provides what,
and why, but that in NO way makes them 'standardized'.
"You may believe that or not", it matters nothing.
