There is discussion at https://en.wikipedia.org/w/index.php?title=Wikipedia:VisualEditor/Feedback&oldid=571087443#nowiki_tags about using the edit filter to block edits adding the <nowiki /> tag in mainspace. However it was pointed out that "the user probably has no way to know what they need to fix in order to resubmit their edit. They can't find the nowiki tag, as it is invisible."
This is because <nowiki /s> (unlike <nowiki>s) are "meta" items in the DOM rather than things VE can edit; merging with bug 56381. *** This bug has been marked as a duplicate of bug 56381 ***
Gah, sorry, wrong bug.
WONTFIXing this bug instead: <nowiki> is fundamentally an artefact of wikitext that users should be (blissfully) unaware of, and Parsoid should "just make work" as needed. Right now this is generally true, and it will get better, not worse, in the future, so this is not needed (which is good, because VisualEditor has no way of knowing whilst a user is editing whether Parsoid will decide to put a <nowiki> in).
