The problem is inherent to Bluetooth, The only way to make it not be like this would be to make things dramatically more difficult to connect to things over Bluetooth.

I'm no expert on the technical side of the protocol, but my BT devices only ever connect to sources they've been paired with.
Why would this be more difficult for hearing aids than for headphones?
Not at all, those ones are permanently in pairing mode with no interaction required and instead it should require manual pairing
