Unspecified bug fixes - I don’t like the tone of that. Please just be honest on what has been fixed Apple!

LOL, Apple's "seconds" should be called "minutes" when preparing or installing the update.

This update did fix something on my side.
My brand new Mac mini M1 would not connect via wifi in the Finder with my iPhone and/or iPad, despite having done all the trusting required.
iPhone/iPad would connect via lightning cable/usb-c cable but as soon as I disconnected them they would disappear from the Finder left panel. Before you guys ask, I had checked the option of connecting via wifi.
Did the update half an hour ago and boom! both my iOS devices now connect via wifi.

2.52 Gb – hopefully it fixes a thing or two
The Sealed System Volume, introduced in Big Sur, is a factor in the size. While the SSV has substantial merit, it also restricts how small a "delta" update can be. This could be a minor patch, but one is still faced with this size of a minimum download.

Interesting that you mention that. Expect things like that to get worse and worse... eventually your Intel Mac will be rendered virtually useless towards the remaining updates for it. Then you will HAVE to get an M1 Mac. I've suspected this was the case for a loooooong while. And, same thing for the M1 Macs (and all Apple devices). That's how they make their money. They eventually render what you have as unusable, if you refuse to stay onboard their profit boat... they push you overboard, then haul you back in when you buy their latest technology.

Just because I'm happy to own an M1 Mac, doesn't mean I'm not aware of their practices. It's better you know the devil's tactics when you choose to play with the devil. Apple... Microsoft... same devil... different suit and tie. :)
I think that is a) a bit dramatic and b) a bit paranoid. Welcome to cutting edge technology. Nobody is sitting at Cupertino thinking about how to hobble your device. Sure it happens at some point but if you look more closely its not malevolence its usually incompetence.
