The starting point was originally that "of course a writing has to have a name", but does it have to? Surely something must be shown when e.g. listing such on the front page of a solution, so what would it be if not the name of writings?

There are use cases where it is impractical to try to come up with a name for an writing, so the decision was made to use the first 300 characters of the first text element of writing's content, whether it be a subheading, text paragraph or something else, instead of the name of the writing. This substitute text is used, e.g. in tables listing writings and on the front page of a published solution. On the writing pages of a published solution, names of writings are simply omitted.
