That is pre-Apple Silicon, before together integration of software and wakeups. I can see a continuously renewed DHCP lease — with nothing else - useful for reducing the time to reconnected to your network, esp maybe on old/slow networks or routers. You can Touch ID and get back in a second, and maybe for 5-10% of users, it was resulting in initial network connection slowdowns or errors with buggy online-only apps. Find My (your device wants to maintain a connection if you have it enabled) is another reason. It must regularly connect (perhaps a long running socket), and I want to be able to remotely lock and wipe my device at any time possible, for example. |

My 2014 Intel MacBook Pro has Power Nap and behaves the same when it comes to radios when compared to my M1. It's not new.

Just because your radio is up, connected to the AP and keeping L2 active doesn't mean your processor/OS is keeping TCP connections up, or even talked to the hardware and updated itself. It's normal.
Find My doesn't keep a connection open 24/7. It pulls the commands the moment system wakes up. I have it enabled and check my devices sometimes, and it's not extraordinary to see "15 minutes ago" or "2 hours ago" for a laptop sitting on the table, not connected to power and its lid closed.
