You see portage telling you that the "screencast" USE flag is enabled by
default, and that it depends on the "wayland" USE flag, and you cannot
disable wayland unless you also disable screencast.

You can just disable screencast. It is enabled as a default by some
desktop profiles, but nothing requires you to use those defaults.

Portage isn't asking you to do anything with llvm19. "A subset of the
following complete expression" just means that portage is providing
additional full diagnostic information about the *entire* package
details. The screencast part is the only issue.

llvm19 is enabled and forced by default anyway.
