...because users, especially application authors, typically have far
greater latitude to make BiC and even SiC changes compared to library
authors. Also, because they don't have the same obligation to make
*everything* fast.

If a user does not use Q_DECLARE_TYPEINFO initially, maybe they just
don't need it, and even if they do, it is probably not an issue to add
it later. If Qt neglects to use it for some type, it can't be fixed
until a major version.
