policy on having the same routines in different library archives?

I've put a port of Slatec together:

Recently I realised that some 110 routines in Slatec
are already present in math/blas, and the Blas versions
seem to be newer.

% ar -t /usr/local/lib/libblas.a | sort > blas.sorted
% ar -t /usr/local/lib/libslatec.a | sort > slatec.sorted
% comm -12 blas.sorted slatec.sorted | wc
     110     110     882

I can see benefits and disadvantages of having same
routines in different libraries. Advantages are
that a user can choose to only install Slatec,
with no Blas, and that no fine tuning of the
distribution is required.
Disadvantages could be extra size and potential
for confusion, e.g. when linking against both

Is there a FreeBSD ports policy on this?

Many thanks
