Composer name for e.g. RealUrl not listed at https://extensions.typo3.org/?eID=ter_fe2:extension&action=findAllWithValidComposerName
Summary
The RealUrl Composer name is not listed at https://extensions.typo3.org/?eID=ter_fe2:extension&action=findAllWithValidComposerName. I did not check other extensions, I guess there is an error in the import action.
This leads to typo3-ter/realurl isn't marked as deprecated at the TYPO3 Composer Repository at composer.typo3.org.
