Like many Wikipedia decisions I feel that this one has
been made
defensively. Short articles collect random unverified crap which they
do not as much when part of a larger article. A larger, compendium
article is more likely to have watching editors, too.
On your 2nd point, you may be right.
However, your 1st point, surely a great big long article have more
chance of finding {{fact}} statement in then one of paragraph or two.
Those that are short and unsourced will at least be obviously so,
whereas the embedded uncited statement can often be left there for
years.
