Impact

Notes

The wt2html: wikitextSize limit exceeded is also mentioned in T286355: Templates expanding to mapframe extensions with large bodies exceed wikitext limits. This one looks slightly different since the two occurrences I found are coming from action API entrypoint discustoolspageinfo

Another example URL is https://es.m.wikipedia.org/wiki/Usuario_discusi%C3%B3n:Kizar

We had some from before deploying 1.40.0-wmf.14.

Before engaging on "what should we do with the limit size for wikitext parse", I think it would be useful to at least collect some metrics around that to understand how often it happens and how we want to handle it. What do you think @ihurbain, @ssastry, and @cscott?
