It's the only one that displays as 'export -T'.  Here, anyway.

Here: MANPATH is: 'typeset -T' like several others.  But it's good to 
know that indeed there are special values that will be treated

which is simply being wrong.

Ah!  That answers my question as to what all this tie-dying is about.  I 
had no idea you can't export arrays.  Marvelous.  You know, when you 
understand why something is, then what it is becomes much easier.  The 
clouds part.
