to be concrete the design enforced limitations are:
- everything with window positioning
- clipboard functionality
- dialogs
- call throttling for obscured windows
- focus
Some have mitigations:
- throttling has some extensions now, unsure whether they're universally supported (don't believe so)
- some environments have clipboard managers
- there's a feature that allows (if supported) restoration of window layout at startup (but without any other features, and without any info to the app)
