The AUR does not fully parse PKGBUILDs because that would require a tool that
can fully parse Bash without executing it, which no one has written yet (to my
knowledge). As such, the current approach fudges it with simple regexes or
whatever that only extract a subset of data. I do not think that includes

The AUR also lacks true support for split packages (again, because there is no
full Bash parser*), which is why the python2-pyside split package is not

A split package builds 2 or more packages. You may optionally install any of
them as needed. It makes sense here to have a split package because both the
Python 2 and Python 3 versions are built from the same source. The only
argument against having a split package in this case is the lack of AUR
support, which makes the package a little harder to find and which requires
some ugly hacks to the PKGBUILD (e.g. "true &&" to trick the parser).

  purpose, quirky scripting language that can only be evaluated by executing
  arbitrary code.
