Is Hot Reload supposed to refresh Swagger/OpenAPI Docs, or is this not supported yet?

Hi, thank you for the great work on MCPO! 🙏

I’m currently using the --hot-reload option with a config.json to dynamically manage MCP server configurations.
While the hot reload seems to detect changes (I can see log messages like Adding servers: or Removing servers:), the Swagger UI (/docs) and OpenAPI spec (/openapi.json) are not updated after the reload.

• MCPO version: v0.0.17 (latest)
• Run command: uv run mcpo --config config/mcp.json --hot-reload
• Behavior:
  • Config changes trigger reload successfully, and servers are mounted/unmounted as expected.
  • However, /toolname/docs and /toolname/openapi.json still show no operations or outdated specs.
  • Restarting the server makes the tools appear correctly.

Questions:

• Is automatic regeneration of the OpenAPI schema after hot reload currently supported?
• Or are there any known limitations or configuration requirements for Swagger/OpenAPI updates after reload?

Thanks a lot for your help!
