Yes, if all the people who want only one set of libraries agree on what that
set shall be (or this can be selected with existing configure flags), this
is the simplest way.

But once you have different people wanting a different single library, this
approach is not longer sufficient.
Also, it might happen that someone doesn't want one multilib dimension, but
they want to keep another one.
E.g. they might say they don't want to support these different
architecture variants, but they need support for both endiannesses (Or you
might hear: hard and soft float, or glibc and uClibc.)
