FWIW, I recall that the main reason for the char limit originally was to
discourage the use of Wikidata for textual content. Simply put, we did
not want Wikipedia articles in the data. Long texts could also make
copyright/license issues more relevant (though, in theory, a copyrighted
poem could be rather short).

However, given that we now have such a well informed community with
established practices and good quality checks, it seems unproblematic to
lift the character limit. I don't think there are major technical
reasons for having it. Surely, BlazeGraph (the WMF SPARQL engine) should
not expect texts to be short, and I would be surprised if they did. So I
would not expect problems on this side.

Best,
Markus
