But the goal totally wasn't to foster development of new scripts by the
community. That's why we never bothered setting up a website to host

Firefox plugins are a huge asset for Firefox. So your comparison rather
speaks in favor of an external plugin ecosystem.

I'm not 100% sure what you mean since I have trouble parsing your
sentence. But LibVLC provides VLC functionality to an application,
whereas the lua API provides functionality to VLC, so they're not quite
Also I'm not sure that the use of LibVLC has contributed more to VLC
than the use of the lua API. Lua considerably lowers the bar for writing
code, and results in much faster contributions that add directly to VLC.

That's FUD on your part. First result in google:

We wouldn't. The locking would be handled by the C part of the API
layer. The semantics don't have to be complicated.
