i would love visual editor to be on Wiktionary and simple Wiktionary
Topic on VisualEditor/Feedback
Wiktionary is especially heavy in its use of templates, which is not VisualEditor's single most developed workflow.
There was a request last year from the English Wiktionary to allow only admins to opt-in via Beta Features, but this isn't possible. At this point, the team is likely to require evidence of community consensus. You might check in with the Swedish Wiktionary to see what they would recommend. It's been (opt-in only) there since late 2013.
