I see that Doormat uses Archetypes content. To be referenceable from
Archetypes content, Dexterity content must have the referenceable
behavior from plone.app.referenceablebehavior enabled. But we don't want
Plone 5 to depend on Archetypes, so the types in plone.app.contenttypes
do not use this behavior out of the box. If you don't convert Doormat
to be Dexterity-based and you require that Dexterity content items be
referenceable from your custom content types, I suppose you'll need to
make sure that you enable this behavior for the core content types when
the product is installed.
