• This is technically a regression in VE, but this has always been the functionality in the mobile wikitext editor
• The __NOEDITSECTION__ marker which triggers this use very rarely, and usually when the section itself contains just a transclusion of another page, e.g.

== Section 1 ==
{{Included section}}
== Section 2 ==
{{Next included section}}

In these cases there aren't really meaningful section edits to be made, especially on mobile

Possible choices

1. Ignore/deprioritise
2. Always show edit pencils on mobile, even if marked as __NOEDITSECTION__
3. Make the lede edit button edit the whole article when page is marked as __NOEDITSECTION__

I think option 3 is harmless and should be easy to implement, since we already have the ability to open the entire page for editing in mobile editors (it's not normally accessible, but we needed it to handle switching editors while editing a section in some cases).

We would like to consider this ticket with the lede edit button T203151 so when we start that work we will return to this ticket

There are 13,000 uses on en.wiki: https://en.wikipedia.org/w/index.php?sort=relevance&search=insource%3A%2F__NOEDITSECTION__%2F&title=Special%3ASearch&profile=advanced&fulltext=1&advancedSearch-current=%7B%7D&ns0=1&ns1=1&ns2=1&ns3=1&ns4=1&ns5=1&ns6=1&ns7=1&ns8=1&ns9=1&ns10=1&ns11=1&ns12=1&ns13=1&ns14=1&ns15=1

But only 97 in the main namespace: https://en.wikipedia.org/w/index.php?sort=relevance&search=insource%3A%2F__NOEDITSECTION__%2F&title=Special%3ASearch&profile=advanced&fulltext=1&advancedSearch-current=%7B%7D&ns0=1

So for article editing this should be very low priority.
