alt Hacker Newswhy is this a good thing? This sucks, it would randomly cause IP conflict in some cases

If they implemented it well, they could have just sent an arp and check if it was already taken.
Then again, I haven't ever been limited by the speed of DHCP servers... Windows is just dog-slow for a lot of things, so yeah, macos just "feels better" generally. I doubt it was related to just this IP thing.

Users would assign it to 'just that network is flakey'.. not 'my hardware is not behaving properly' because it works elsewhere.

There's gotta be a bit more subtlety going on here. DHCP leases include a lifetime:
It's possible that older versions of macOS persisted the lease details across reboots and reused unexpired leases on subsequent network reconnections.I am also fairly sure that I have never personally seen any evidence of any OS doing this, including macOS, including when it was still called Mac OS X. I suspect macOS simply brings up its networking stack earlier in the boot process, so the network connection is more likely to be ready and waiting by the time the desktop loads.
