Palm rejection improvement when handwriting

I've been using the handwriting feature in Notion iOS with an Apple Pencil since it first came out and I've always found it quite excellent. I wish the handwriting area was full screen (that's my number one request), and to my surprise I found that I can write directly in the main window if I turn on the pen mode but don't turn on the magnification lane. I discovered this while using Duet to turn my iPad Pro into a writing tablet for Notion macOS which is brilliant. Although I notice that working in magnification mode seems more actuate than plain pen mode with magnification.

However lately, for some reason I've been having way too many palm rejection issues. If I just brush up against the glass, which is easy to do in magnification mode, (at least for me it is), is messes up the handwriting recognition.

TouchNotation has an adjustable area on the screen for resting your hand. It's a big square that can be moved and resized. Please take a look at their solution and improve upon it. Something like that would be welcome, especially WHEN you guys go full screen with the high quality handwriting recognition, because you are going full screen like StaffPad, right???!!! Please say yes. Please tell me it's coming soon. Thank you!
