They're allowed, they're just not generally delegated.  I believe that there
was some specific IANA policy about this, and it boiled down to something
like "these are special.  we're not handing them out without good reason."

The canonical example of a single letter delegated comnetorg 2LD is x.org.
Obviously someone liked X11.
