No.

  You have a single Python Script "getAbsoluteURL".
  It takes a path, resolves the path to an object using
  "restrictedTraverse" and returns its "absolute_url".

  Its Proxy role ensures, "restrictedTraverse" will not
  fail.

Someone explained that ZPT should only be used for presentation
and proxy roles were more associated with logic rather than
presentation.
Personally, this argument did not convince me. But the issue
it not urgent enough for me that I would try to implement
proxy roles for ZPTs.
