>The Big Sur 11.2.2 update is a good example of what’s almost a null change, yet requires ... 3.1 GB for an M1 model.

What Is the change?!

Official site doesn't have entry for 11.2.2 or am I missing something ?

GUI says this: macOS Big Sur 11.2.2 prevents MacBook Pro (2019 or later) and MacBook Air (2020 or later) models from incurring damage when they are connected to certain third-party, non-compliant powered USB-C hubs and docks.

Then for more details it sends here: https://support.apple.com/en-gb/HT211896

What about massive writings to SSD? has it been addressed? Or it's not a problem?

PS: GUI says for my M1 it's 2.17GB and article says 3.1 GB who is correct?
