My main goal is documentation.

Typing difficulty is largely a property of the editing tools rather than of the character itself. Editors already provide shortcuts for characters that would otherwise be inconvenient to enter, and those shortcuts strongly influence what people actually use. For example, typing d͡z is usually much harder than inserting a TAB character, but the source editor provides d͡z through “Special characters > IPA”. If tab indentation were considered desirable for a particular use case, making it easier to insert would be a tooling problem rather than a limitation of the format syntax.

Yes, since there is apparently no real-world use case. This is working as intended.

The syntax might generate wikitext, but that doesn't mean it needs to support all features that are supported in wikitext.

An extension like TemplateData cannot and probably shouldn't influence how wikitext behaves.

The issue is that it's currently possible to write a template like this:

@matmarex The format field only indicates a preferred format for VisualEditor; it does not restrict how users write the template invocation in wikitext. When editing wikitext, users can still choose whichever format is most convenient for them.

@Anirudh_KK Thank you.

@Pppery Thank you!

@Aklapper Thank you. I did not know about Requesting wiki configuration changes, in the future I definitely will.

Here is another use case of the empty-name parameter (see the {{unique coins}} template on enwiki):

we are very slowly making wikitext syntax more consistent and less surprising

Before changing anything, we should ask: What for? What will the current wikitext syntax gain from removing the empty-name parameter?

Thanks a lot!

@Pppery The talk namespace should be called “Disputatio Moduli” (you can look at Disputatio Formulae or Disputatio Fasciculi for similar examples – the first is the equivalent of “Template talk” and the second is the equivalent of “File talk” on enwiki)
