Yes, if you have one package that has both API and non-API Classes in
it, then x-internal wouldn't help.
I didn't realize that was the case you were talking about, so,
something has to be done there no matter
what the new name would be, so just as well be 'internal').
You raise some interesting points about x-friends vs. x-internal that
I was not aware of.
In fact, I thought it was the reverse ... that x-friends automatically
meant it was
x-internal to all (but the few named as friends). So, I learn
something new everyday.
But, I think x-friends is only appropriate for plugins within the same
component feature.

Guess we need to update that document to include JSF and JPA.
The good news is ... I have a solution for the Christmas tree effect
I've been preparing,
and almost ready to send a note about!

Re: [wtp-dev] Convention for "internal" packages
Correct me if I'm wrong but x-internal applies at the package level, not
the class level. How does one differentiate API from internal classes
if they are not separated into different packages by name? And if this
is the case, what would be better as the differentiator than "internal"?
Also, x-internal has several serious problems that I can see. First, it
only marks something "discouraged" rather than "restricted". In JSF, we
turn off "discouraged" since otherwise our WTP dependencies light up our
warnings log like a (yellow) Christmas tree. However, we do respect
strictly the "forbidden" flag, which is what you get if you use
x-friends. Second, x-friends is actually *overriden* when you use
x-internal.
