status of PKCS#11 providers?

[lists <lists@xxxxxxxxxxxxxxx>]

Hi all,

I happily use libp11 as a PKCS#11 engine for OpenSSL in my projects.

Now I need to experiment with PKCS#11 *providers*.

In my understanding the most promising GENERIC pkcs#11 provider is this 
one: https://github.com/latchset/pkcs11-provider

Any other project at a better stage? I tried some other but they all 
seem at early stages, abandoned or intended for specific hardware, or 
with some quirks.

Can anybody confirm this? Thanks - Umberto
