This is an irrelevant issue based on a premise that is absolutely and totally wrong.

There is NO CHANGE OF CONTROL due to SRV, none, zip, nadda.

If a party controls the DNS information for a host it controls all name based inbound connections to that host absolutely and irrevocably.

Devolving additional functions to the DNS does not entail any change of control because that control is already lost.

If I control example.com I control the inbound email, web, ftp services. If you are binding to a raw IP address then SRV is not exactly going to be very relevant in any case is it?

The Internet is the DNS, the IP based packet transport is mere plumbing. 

If someone wants to be a first class citizen on the Internet they have to own and control their own DNS service. Otherwise they can have no meaningful control or security. 

DNS names are not free but they are exceptionaly cheap. If you want to put up some service and your ISP refuses to allow you control of the DNS there are plenty of DNS service providers who will be happy to help.
