Andreas Sewe commented on MSITE-582:
------------------------------------
Sounds good to me _if_ the following boundary case is supported as well:
bq. I want a child to remove D > E > F. The child thus defines C, which results
in A > B > C being picked for its breadcrumbs.
That being said, I don't want to be the only one who has a say in this issue.
Maybe you should take this conversation to {{d...@maven.apache.org}}.
> Make it possible to remove breadcrumbs in child projects again

> Key: MSITE-582

> Issue Type: New Feature
> Components: inheritance
> Affects Versions: 3.0

> Currently a child can only add more breadcrumbs. There are situations,
> however, where it is desirable to remove some or all of the breadcrumbs
> defined by the parent, in particular when the Maven project hierarchy doesn't
> match the _natural_ hierarchy of the site. See
> <http://www.mail-archive.com/users@maven.apache.org/msg117974.html> for an
> example (also attached).
> One way to do this, without requiring changes to the {{site.xml}} format and
> with only minimal breakage of compatibility, would be to simply use the
> child's breadcrumbs wholesale whenever they are a prefix to the parents.
