What about IPv6 connectivity when I add an IPv6-only node in IPv4-only
domain? None. And there doesn't (necessarily) need to be that.
Obtaining the IPv6 connectivity is always the first step.

I'd like to hear why anyone would care about MIPv6 in IPv4-only domain.
Get IPv6 address with 6to4, then your domain isn't v4-only anymore.
Needless to say, I don't get your reasoning at all. Please help me
understand.
