My first reaction is preferring the first approach, which seems to
give more possibilities to us. 

For instance, the INFO command could be
THE thing we need for giving the user information about what's going
on. We have some usability reports about the non-intuitive use of the
installer frontend...so there's maybe a possibility to improve that

Making this INFO command optionnally frontend-dependent (ie
displaying different texts, depending on the frontend) could be a way
to do this. Of course, in such case, a fallback text should exist for
frontends for which no specific text exists.
