TYPO3 Core

I think that there is a problem when the site configuration remains in /config/sitename, but the site in the page tree is deleted.

I did the following steps:

• Created page structure for site A (site with site root)
• Created site configuration for that site in sites module

After that i wanted to recreate the page structure in a second tree (but with the goal to use the same domain as for site A because i want to replace that later).

• Created page structure for site B
• Deleted page structure for site A (because i did't not need it anymore)
• Created site configuration for site B

In the end i got a page not found error in the frontend, but the configuration in the backend looked correct (page structure for page B and site configuration for siteB). In the end i recognized, that the pagetree for page A was deleted, but the site configuration in the config folder still exists. But the site configuration for siteA was not visible anymore in the backend.

I think it would be good if the unused site configurations are somehow visible in the backend, or the site configuration is deleted when the tree for that site get's deleted.
