The server is responsible for updating the contents of the context
(since it's dynamic and not static). Surely you do not want to rely on
the bean writer to manage it correctly in order for your code to work
properly. And the bean developer does not want to keep track of it just
to allow the server to access it (the context may be useless to the
bean).
It's not a good idea.

This is not correct. In s. 9.4.1 ("Container managed fields") the
following types are listed as candidates for CM:
"The Bean Provider must ensure that the Java types assigned to the
container-managed fields are
restricted to the following: Java primitive types, Java serializable
types, and references of
enterprise beans� remote or home interfaces."
The context is not primitive, serializable or reference to enterprise
bean or home interface.

Considering the above this is kinda pointless. In any case there might
not be a context field at all since the bean may not care about it. You
might have confused this with stateful session bean management, but
that's another story altogether and the reasons for managing the context
in the bean there is quite different.
