[MEGATHREAD]: Future improvements to the Win32 Console API / Command line north star

[DHowett]

⚠️ work in progress 🏗️

This thread makes no commitments to actually changing the console API. The party line remains that we're not making any changes to the API any time soon. Rather, we do need a place to aggregate changes we might want to make, should the opportunity present itself.

The Console should support new APIs

• Need a reasonable way to either cancel ReadConsole or poll for text input #12143
• Reading extended attributes (RGB colors) from the screen buffer #292
• ...

"CLI apps need feature detection"

• WT should set COLORTERM #11057
• DISCUSSION: Is my app running in Terminal? #7434

Assorted

• A conclnt nuget package might let CLI apps use new APIs or new versions of the APIs. That's a thought.
