Are you saying an author should discover whether or not it's possible to create a FP FBO by trying and if the FBO is incomplete after the attempt, that's an indication that it's not supported? I don't think that has precedence. Seems like it's much better to use the extension mechanism. If the attempt to enable the extension fails, then it's not a feature that can be used.
