Does this actually work in real life? Considering the solutions I found 
doing my quick search, it seems the AP vendors are implementing all kinds 
of solutions to trick the client that it's just one single large network 
with a single AP, even though it's a lot of them.

For instance: 
https://help.ubnt.com/hc/en-us/articles/205144590-UniFi-What-is-Zero-Handoff-

So while I would prefer a solution in the end with make-before-break and 
seamless handover without breaking the IP layer at all, this seems to 
involve quite a lot of new functionality both from the Network (which is 
doable) and from the client (also doable, but a lot harder, especially 
within current charter).
