Historical cruft?  The evolution of the languages have been different.
The presence of strong vendors in the CL camp does (IMHO) work as a
disincentive to community wide standardization.

On top of that add the dwindling support for CL as a whole,
irrespective of the technical merits of the language itself.

Things are changing, yet slowly.  This is just the way things are.

As for  "widely used though non-standard libraries for CL for "doing
stuff like internet programming", you can check the CLOCC
( Not much, but it is there.
