The difference is that MENU_CALLBACK items are really just invisible
callbacks now; i.e., plain router items, not having any kind of menu link.

For edge-cases like the given example, in which you have a router path that
does not contain any dynamic path argument placeholder (%), you want to use

We actually discussed whether we need a new constant, but since a new
constant would be identical to MENU_VISIBLE_IN_BREADCRUMB, it would just
have another name.
