Posting Etiquette
-
Ask the main part of your question in the title. This should be concise but informative.
-
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
-
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
-
Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

I think you shouldn't bother. First, as another user already said, the normal user does not look much at the address bar. Second, how will you work with deletions? Say user created 4 categories 1-4 and deletes category 2. Now you either have a hole or you "reindex" the categories to 1-3, which is probably bad since it breaks any bookmarks the user created.
Deletions would work the same way as with a regular autoincrementing ID, it just always goes up. All it matters is that it doesn't expose how many other IDs are in the DB
