We experimented with this and had quite a long discussion.
The conclusion was that we didn’t want to impose wiki contributor a too-complex set on rules regarding the tagging.
Another sane approach would be to create a wiki page listing scripts for which X/Y is optional.
Adding too many of those would also compromise wiki.js’ native tag browser (as all those tags fall into the same bucket and cannot be categorized as with other meta-data structures).
You can still see an early draft of the gallery that played around the idea of (way) richer tagging and filtering.
This is a brilliant idea!
