99.9% of users don't have/use "server-side sieve filtering", so every new mail comes to the inbox only and the user might move it to a different folder later on. Because the workflow of most users is like this, you will have a hard time "going against the grain" if that makes sense.
My practical recommendation to you would be to just use a single inbox like everyone else if it's not critical for you to have "server-side sieve filtering".
I know it's hard sometimes to not have something work exactly like you wanted it. It happened to me many times also. Going with the majority is much easier and less time consuming than going the other painful, lone, hard route imo. Anyways, hope you find a good solution :)
