If one-sentence articles are considered a problem, that seems like a reasonable choice for Wikipedia to make, but it would apply to human-written and bot-written articles.
Most articles started as stubs. At the moment many language versions of Wikipedia have different opinions about stubs.
e.g. german wikipedia don't allow stubs anymore and the admins delete & reverts more pages every day than new ones are created. It's maybe a cultural problem as such admins identify themself with 'their articles' and don't allow any changes.
The question of course is in how to determine when a short article is a stub. Some short entries are sufficiently complete for the purposes of WP, whose English guidelines say "there are some subjects about which very little can be written."
> Muati is an obscure local god in the Sumerian pantheon. He is associated in some texts with the mythical island paradise of Dilmun, and becomes syncretised with Nabu.
That's unlikely to get much longer. For one, the "Dictionary of the Old Testament: Wisdom, Poetry & Writings ..." says "Muati, a god about whom we know very little."
