Maybe we are talking about different things.

What I'm talking about if that applications on phones keep working even if
the phone witch between mobile and wifi connections or moves from one
wifi to the next.

Similarly laptops can move from one wifi to the next. VM running on a laptop
can be taken from one wifi to the next and keep working, etc.

Nobody expects to reboot a phone or laptop just because you connect to another
wifi. In the case of the VMs running on my laptop, they are bridged, so they
pick up new addresses even though there connections stay up.

Now the question is we can also make this work for prefixes. Can I give
my VMs a separate prefix and expect that to be updated as I move around.

If vendors of network equipment don't care about this, then there is always
IPv4 and NAT. Or maybe IPv6 and NAT.
