If there is a contention or disagreement between different API styles,
it may be wise to seek opinions on python-dev or python-ideas.

I'd point out that the "ssl" module itself seems to have evolved from a
trivial wrapper API (in the 2.5 docs I can only find a single
3-parameter function, socket.ssl()) to a more comprehensive API in 3.2,
because people ultimately need the functionalities.
(and yet the ssl API in 3.2 is still much less featureful than M2Crypto
or pyOpenSSL are)
