It's not really that moot.
Firstly, as pointed out. Follow the procedure, and you can be seen to be behaving predictably.
Do something different, and maybe you start to cause greater concerns.
Secondly. What if your planned route is relatively short, or comm fail is quite late? In the time it takes to get a pair of jets to intercept you, you may already be at your destination. If you end up at the appropriate fix, descend as appropriate, and arrange your approach to be close to (as practicable) your planned arrival time, then hopefully all should end well.
(I shall now duck for cover, and don anti-flaming suit)
