Yes I read all that stuff. The big one is this.
System firmware: UEFI, Secure Boot capable
TPM: Trusted Platform Module (TPM) version 2.0
Older devices are screwed. Even 7th gen Intel and AMD Ryzen Zen1 processors are currently off the list. I have a device which will take these requirements but they are not pervasive. W11 will be mainly for new machines.
W11 will run both Android and Linux apps as MS works to make it cross platform. This has been something they've been working on for years now, not just for tablets but to make MS cross compatible in a range of areas.
As for the MS account stuff....
It also does that with W10 home now. They removed the option for installing without a MS account. I registered W10 home with my new little machine I just bought and I had to use my Hotmail account. As soon as it was set up, I fired up Powershell, Admin, issued a create new account, local, command, then made the local account admin. I then removed the account which they insisted I register it with. Works perfectly for updates etc... So you don't have to get Pro and you don't have to be hooked into the MS ecosystem. They only make it hard, not impossible, which catches the majority of the tech unaware.
Apparently they've done something to sort out the multiple monitor response when you disconnect and reconnect. So it's certainly not just Tablet based.
