Filtering out @_exported import symbols from symbol graphs

is there a way to exclude @_exported symbols from symbol graphs?

APIs exposed via @_exported import are included in the module's symbol graph because they're part of the module's API. You can't opt-out of this behavior right now. Can you elaborate on why you would want to omit symbols that come from @_exported import?

i need to know which module (and eventually, which package) symbols really belong to. if symbols from ReexportedModule show up in ImportingModule, they will be duplicated between the documentation for ReexportedModule and ImportingModule.

aside from the duplication, they also have identical USRs, which causes a whole host of problems related to ID collisions. if we solve this problem by uniquing based on symbol ID, then this opens up the possibility that symbols could be “kidnapped” from their original namespace and moved to a package+module scope they are not originally from.
