One major difference between Wikimedia Commons and every other Wikimedia project is that not only are redirects essentially useless, they’re also annoying as [redacted]. Now this wouldn’t as annoying if the MediaWiki Upload Wizard would ignore them… but it doesn’t, nor does it actually warn users about the fact that they just selected a category that directs to another category. However ignoring redirects would create its own problems altogether as the redirect would make more sense or is the same name as its equivalent page in the English Wikipedia so without these redirects many users wouldn’t even be able to find the pages they're looking for. However we don’t want the wizard telling users “you shall not pass”.
So the solution is actually simple, let’s say a user types in “Turkish museums” in the MediaWiki Upload Wizard they should be automatically redirected to “Museums in Turkey”, currently only a bot 🤖 does it but then the files still end up in the redirect category first. Now redirects are very handy if they are utilised correctly, someone typing “Museums of Turkey” might not know that it's “Museums in Turkey”. Now visualise this, the uploader types in “Turkish museums” in the upload form, they press “enter” and suddenly the correct “Museums in Turkey” is selected. This way category redirects could be useful rather than a mere hindrance. This is similar to what Hot-cat does today, it simply adds "the correct" category when a user wrote the redirect.
