<pre wrap="">I thought the whole concern here was that external projects consuming OpenSAML *must* depend on stuff in the -impl modules, since that's where all the good stuff and actual functionality is located.

Ergo there's a problem: They have to depend on unstable stuff, practically no way to avoid.

Ok. I think our contract there is clear, whether it's good for anybody or not.</pre>

I agree, I think it's currently *clear*. Just not good, for the
external projects.<br>

But there *are* interfaces and base classes that I think we could commit to but haven't yet. Meaning, yes, it's still not a real answer, but where we do have things we can move into the API, we should try and do that.</pre>

Again I agree. But all of those we could move are probably about a
5% percent improvement. All the good concrete stuff (read: usually
hard stuff to implement) is going to stay impl. And people are not
likely to implement their own trust engines, message
encoders/decoders/handlers, profile actions and probably a zillion
other things, just to avoid this. They're going to use our impls,
and so they're going to be dependent on unstable code. (Or else we
do as we implicitly have been, acknowledge this situation, and
defacto treat those as API, and don't make breaking changes outside
of a major version. We technically *can*, but practically speaking
we don't.)<br>
