Without further clarification, I don't see much difference between marking libraries "deprecated" or "obsolete".

"Deprecated" means that the library will be removed in the future. "Obsolete" does not. Users of deprecated libraries, therefore, are encouraged to transition away from using them. Users of obsolete libraries don't need to do anything; the use of obsolete libraries is discouraged in new code.
