I do not expect this to cause issues - you might see an error in the log
at tunnel teardown time when OpenVPN tries to remove the address that's
already gone, but nothing else will happen.
As soon as the tunnel has been set up, OpenVPN will not actually *notice*
if you mess with routing or interface config on the operating system side,
so it's safe :-)
What I'm not sure about is if something will explode if we do not do IPv4
at all, read, "all the stuff that cares about IPv4 is not initialized",
as "something might rely on it". But this is really a few days of working
through the code and making sure nothing breaks (and adjusting options
that mandate v4 today), no "we *know* that it cannot be done!" stuff.
