If a large framework (or library, application, etc.) has optional parts
and some users may not want all parts, it would make sense to break the
framework into separate physical assemblies. However, if internal
access is specified in the monolithic framework, a problem arises
because changing internal access to public changes the design
intention. Something other than public is required, yet internal
doesn't work anymore (even though the logical design of the code has
not changed).

The large framework is still logically one unit, but it has been
physically arranged as two or more assemblies strictly for efficiency
or flexibility. Why should we not have a way to define an internal
access level for the _logical_ unit? In an imaginary future version of
C#, this might be something like the internal access modifier scoped by
namespace. . .

Is there any way to accomplish what I'm after in C# 2.0? Thanks.
