Actually, automatic should imply OPTIONS.

With REGISTER, as we have discovered, the proxy overrides the expiration time
to 600 seconds and the UA stack is obliged to follow, so REGISTER is not good
as a keepalive method in this case.

They are unsuccessful from the server side, but the interval is followed on the
client side. I should think about authenticating OPTIONS; at least it should
not break anything. With the keepalive usage, there's a clear benefit in
keeping the OPTIONS request small, so it does not include the authentication
token obtained by REGISTER. Maybe the stack should learn to keep it after the
first such error status.
