Dedicated classes make it possible for programmers to process the data without having to interrogate and external source in order for code to decide how to process the  value.
For example, LC Name Authority and LC Subject Authorities have known uses. Same for Mesh.
If some local extension needs to be interrogated before use in order to be sure what it is this will slow down things considerably.
If a local classification scheme could be a sub-class of a type classification scheme (and not just a generic bf:classification) then this could solve the issue.

Thanks,

It's not clear to me in what way the scheme outlined would prevent efficient operation. Perhaps you can elaborate?

How do we express a local classification scheme?
