>What exactly do you mean by a "module"?

A feature by a different name and from the feature provider point of view.
I could have just as well used "Feature" instead of "Module".  I just
assumed that the "Mod" in "ModAX" was for "Module".

It is just my style, ying and yang sort of thing.  I did not see any
compelling reason not to have it and there are some benefits such as chain
(as in chain of responsibilities) management.

True if the feature in question is mandatory.  Code ends up a little messier
if the feature is optional.  If I just wanted to install different handler
types depending on whether a feature is available or not, we end up with
many try-catch islands.

Anyway, I like your latest proposal.
