facepalm. First, it is generally better to apply performance improvements to the existing framework than to create a new one.

Second, different is not always better. This will increase call performance, but will incur a (de)serialization penalty, limit parameter types (likely to scalars and read-only hashmaps), and make debugging more difficult. And beware of telling the OS that you implement this protocol, or you will have created an XSS attack vector on your native app.

Whenever you break new ground, don't fool yourself into thinking that you're the first person who has had an idea, and make sure that you sanity check your work.
