Important: #86895 - Route aspects take precedence over requirements

See Issue #86895

Description

Route requirements are ignored for route variables having a corresponding setting in aspects. Imagine there would be an aspect that is mapping internal value 1 to route value one and vice verse - it is not possible to explicitly define the requirements for this case - which is why aspects take precedence.

The following example illustrates the mentioned dilemma between route generation and resolving:

routeEnhancers:
  MyPlugin
    type: 'Plugin'
    namespace: 'my'
    routePath: 'overview/{month}'
    requirements:
      # note: it does not make any sense to declare all values here again
      month: '^(\d+|january|february|march|april|...|december)$'
    aspects:
      month:
        type: 'StaticValueMapper'
        map:
          january: '1'
          february: '2'
          march: '3'
          april: '4'
          may: '5'
          june: '6'
          july: '7'
          august: '8'
          september: '9'
          october: '10'
          november: '11'
          december: '12'

Actually the map in the previous example is already defining all valid values. That’s why actually aspects take precedence over requirements for a specific routePath definition.
