Hi,
This page says:
Is this the best approach? No, but it is the best approach with the current technology. A very significant MediaWiki rewrite is required to make this possible on the system level. This functionality has been requested from the start 18 years ago, but not much was done simply because this is a very hard problem to solve.
I agree with all of this.
Let's imagine that this rewrite is done. How should it look like?
Over the last year or so I wrote this: User:Amire80/Global templates draft spec. The people who participate in the discussion on this page should be interested in this. If you just read the introduction and the "proposed solution summary" it's already good, but if you can read the whole thing, it's even better.
I'd really love to hear your opinions about this. (And if anyone can translate to French, Spanish, German, Russian, or other languages, it will be even nicer. Just use the "Translate this page" link at the top.)
Thanks!
