[Foundation] Growing Concerns for Client Developers

Some very good points, all very valid.

1) Core Protocol KISS

2) Extensions are differentiators between on Jabber offering versus another.
Do not limit innovation, by regulating extensions.  When multiple
implementations of an extension exist, then the parties that have developed
those extension may choose to collaborate to provide a common protocol.
This protocol extension can then be officially adopted by the foundation or
not.

3) Suggestion that a standard way for a client to be asked what services it
supports may be something that should be added to the current protocol.  I
am sure the basics for accomplishing this are there just needs
formalization.  Then it is up to the client to interact in a friendly manner
with another client.
