Yes and it is a good solution for the system maintainers but this should be an action editors can do in the TYPO3 backend by themselve.
Your extension is great for an initial import of redirects or for system maintainers but often editors want to import multiple records in their daily work. Currently they have to do this manually or instruct us to do it.

I think it would be a good idea to check if this really makes sense first. It can be problematic to

• give editors access to redirects management
• create lots of redirects (managed via TYPO3, specifically PHP versus within webserver config)

While - of course - this is up to the integrators and site admins, it is not necessarily a good idea IMHO if TYPO3 should supply features which may cause problems if not handled well and are prone to be misused and not used in their intended way.

In the redirects documentation we explicitly added some paragraphs to warn about performance and how to handle editors - this was after much discussion because we did not want to unnecessarily point out problems - but fact remains redirect handling does require some knowledge about SEO etc., too many redirects via sys_redirect will become a problem (because of performance) and - in general the question is whether managing of a large amounts of redirects in the redirects module is such a good idea or they are better maintained in the web server configuration or .htaccess (for performance reasons).

In any case, I would try to focus on fixing bugs first in redirects and site /slug / routing handling and performance issues in managing redirects before starting with this. Not that I want to stand in the way of any cool new features, just something to consider.

see documentation: https://docs.typo3.org/c/typo3/cms-redirects/master/en-us/BestPractices/Index.html

see also issue on performance: https://forge.typo3.org/issues/90143 and this is not trivial to solve and there will most likely still be performance impact with large number of redirects.
