Is erlang too small?

Would the maintenance cost to actually include common libraries like
xmerl and edoc be prohibitive?
The Java Community Process and Python Enhancement Proposals are examples
of two very successful initiatives that have helped increase the
productivity of developers that use those languages. The inclusion of
common libraries(xmerl) sets a standard that provides consistency in the
development of software that deals with XML. Another benefit of rolling
open-source library projects into the languages core is that these
libraries receive an immediate increase in visibility. This increase in
visibility often leads to major improvements to the libraries after they
are initially included. In addition these additional standard libraries
increase the marketing power of a language by providing new features
that can lure new developers into trying the language.
The CPAN approach does provide a rich set of libraries, but it suffers
from several key shortcomings. First their are often lots of libraries
that do similar things, which often leads to a lack of consistency in
how common tasks are accomplished. Secondly because developers have to
go out of their way to actually install a CPAN module leads to many
modules that are not used very often and suffer a lower quality as a
In summation as an Erlang developer I would like to see its user base
continue to grow and I feel including additional libraries would help
that cause by making current developers more effective and increasing
the features that might convince new developers to give the language a
Thanks for Erlang/OTP,
