In the course of less than an hour I have come across one speedy delete notice, two Wiktionary move notices, and a VfD notice, all attached to new short mathematics pages. All of which would properly be labelled stubs.
The Wikipedians responsible don't have specialist knowledge - they seem to feel that remedies for stubs other than stub notices should exist (and in one case, thinks that if it looks like a typographjc mess, it must be nonsense).
As far as I'm concerned, Wikipedia still needs stubs to grow, precisely in areas where it is currently weak.
