Thread:VisualEditor/Feedback/Wikivoyage parser extension tags and the VisualEditor/reply

Replies to individual points:

Yes, eventually. However, this will involve adding a custom "node handler" (data model item) for these tags, and an "inspector" (UI/interaction item) for what goes in them.

Not yet, but they will be (using the regular parser hooks).

It will change the nature of the problem. :-) Either way is fine, though we'll tackle Templates ahead of project-specific extensions, so that might sway you one way or another. The use of Lua shouldn't make a difference to our Template-handlers.
