For what reasons?

This may not be easy to achieve for PTVs.
An option for the admin to set a variable to control this is simple

Therefor I think it is important to set a good core behaviour for
preference of PTVs with identical name.
For any application where a set of PTVs is set at the beginning of a
page, and where content of any sort may be added later, it is
desirable that the PTVs should be evaluated with their first
This is true for instance for all Cookbook pages which carry an info
section consisting of a number of PTVs.
This is true for applications where category tags of any sort are
added and updated at the beginning of the page.

I suggested a specific simple core change there (yet without an
admin switch to change the behaviour so a later PTV will override
