So it should be in the .di file.

You don't throw the error and that's it. What's the worse thing that
could happen? A bug in the code. You go and you fix it. If there's no
bug in the code and the compiler yells at you, that's very annonying
(like in the example you showed).

I still can't see what's the problem if the error were not issued by the
compiler and static this would be run in the order defined by
dependencies found in static ifs.
Until I see a real example where if the compiler doesn't issue an error
then something *really bad* would happen, then I won't be able to give
much more opinion about this. :-(
