[development] hooks after hook_menu CALLBACKS called, but before page rendered

[_craig]

I want the opportunity to affect the breadcrumb trail already set by modules
that used drupal_set_breadcrumb in their menu callbacks.  I want to have a
final say on what the breadcrumb will really be.  

For example, I want to be able to change a breadcrumb that says "Home >>
created >> by >> a >> module" to "example.com >> created >> by >> a >>
module".

Currently taxonomy_breadcrumb works only for nodes and not all paths where
breadcrumbs are shown.  The HEAD version of my module uses hook_nodeapi to
call drupal_set_breadcrumb (hook_menu in 4.7).  This strategy works well for
node types but doesn't get me anywhere for paths that aren't nodes.  This is
why I want an opportunity the module have the "final" say on breadcrumbs
after all menu callbacks have been called (but before "print theme('page',
$return);" in index.php).  Again I'll highlight the distinction I missed
earlier: I specifically mean menu CALLBACKS and not simply hook_menu calls.

there is no such hook. perhaps you can tell more about what you are doing
and we can suggest an approach, or create a new hook.
