If libcurl would get any such plugin architecture it would of course simply
use the plugins that are available when run and thus different systems and
different operating systems would get installed with a different set. Then
there could even be different code bases for different operating systems if
that is the clever choice.
These days we have a fairly good internal "API" for the protocols so it would
probably be easier to reach there now than it was a few years ago. I'm not
saying it is complete or would suffice at this point, only that the foundation
is already there.
I would assume a plugin-based system would simply use dlopen()/LoadLibrary()
at global_init() time or similar, and then libcurl internals would use the
externally provided protocols exactly as it would use "internal" protocols.
Perhaps ODBC would even be a good protocol to start something like this
