Improve error messages in core

**Description**
Currently routes lacks proper caching support.

**Proposed solution**
Add configurable caching with sensible defaults.

**Priority**: Low/Medium

The issue does not name any files, tests, or entry points. Start by locating the routing code and existing configuration or caching behavior, then determine how configurable caching should work and what sensible defaults mean. Done means routes have the requested caching support with documented defaults and coverage for the relevant behavior.
