As you can see, there are a number of requests package extensions that ship with arcpy.
I have to often deal with client certificates in PKCS12 bundles (.p12 files) in something of an edge case for managing authentication to web services.
requests_pkcs12 is a pure requests extension, well maintained, no problematic dependencies - it would fit easily right along side gssapi, kerberos and oauthlib.
Such an effortless add, and would make my life so dramatically easier - please help!
