As a neuroscientist focused on intracortical recordings, these can be useful for certain clinical diagnostics but they’re quite limited in terms of signal quality. They signals are analogous to listening to an orchestra from outside the building. You may be able to tell that a song is playing but you lose the vast majority of the detail, and what we can learn from this is somewhat limited. Noise from facial muscles is another huge issue if you’re focused on the brain. Some interface devices focus on these signals instead for silent speech decoding etc. that can work, but the applications are still somewhat niche.
