TPM is still part of what they’re calling “minimum system requirements” but they’re allowing you to install without it. There will be big scary warnings though and they’re threatening to not provide support.
Time will tell what happens. I believe if they see a significant portion of Windows 10 users on legacy devices without TPM upgrade to 11 they’ll continue to support it because the data they suck up is more valuable to them than the effort to support it.
You should open a fresh issue for questions like that instead of asking on an unrelated one.
