TYPO3 Core

If the page type decorator is at least once, unmapped page types silently get truncated and produce faulty URLs. While I understand the purpose of this, I think someone should be able to disable this behavior, e.g. by setting default: null.

Additionally, page types can't be re-mapped in an URL (e.g. where the page type must be at the beginning of the route), any other argument doesn't get replaced.

Example:

routeEnhancers:
  MyIdentifier:
    type: Simple
    routePath: '/{page_type}/{uuid}'
    _arguments:
      page_type: 'type'
      uuid: 'uuid'

With that configuration, page_type is replaced (and processed), but uuid is not replaced and the value gets attached as a GET argument.
