Actually shouldn't the strict selinux policy cover this type of thing
much better. Not only just while BT is running, but only BT the app can
listen on that port range?

yes and that request should just be the bind(sockfd, my_addr, addrlen);
The kernel should be able to decide to grant that request based on the
information it has being a "trusted" app(selinux context label), run by
trusted user(uid,gid,selinux domain).

It would be slicker if only the BT app could use those ports and you
didn't have to dynamically punch holes in the firewall.
