Yes, but that looks to me like a good reason to keep ours, not drop the

The issue might be to reconsider/clarify the purpose of the project; are
the lib* wrapper a workaround, or extra features?

While I don't think we should add more glue to extra libs all over the
project, I still think it's good to have reference implementations
available (see the points in my previous mail) as long as it's not much
code and that they are not the default when our implementation is good

Anyway, just my opinion/comments, any decision is fine with me.
