I don't see a limit. Typically we have currently this kind of plugin
interface avaialble for C++ :

Generic tools (view, batch, import, etc...)
Webservice tools
Image editor
File IO (aka file loader/writter)
Raw import
BQM

Here i write demo of C++ plugin interface, with code examples.

I plan to add more, as face engine for ex... But for this one, we need
to see current GoSC 2020 project done.
