It could frequently come out a big problem of collisions with existing
templates with different code. I feel that synonimous templates, with
different features, are a very subtle and harmful touble. This raises the
long-standing problem of "redundancy and coherence" so deeply afflicting
anything into wiki contents, but extension tags. It's impossible to leave to
the willingness of bold, sometimes unexperienced users, the hard task to
align templates. Exactly the same, for experienced users.
But perhaps, a "SharedTemplatesExtension" could be built, ensuring a common
repository of template routines, matched with common names. I can't imagine
how this can be done. :-(
