There is only zero incentive if the filter detects AI music reliably. It's still a race between effective detection and cost to generate content, isn't it?

Suno et al don't really have a incentive to hide the fact that their tracks are generated using AI. Quite the contrary, the only way they won't get sued to death by UMG and the other big labels is to disclose AI generated tracks.

Doesn't Warner Music own Suno?
