I see vulkan 31 times in use.local.desc, with slightly different
descriptions. Most notable difference:

app-office/libreoffice:vulkan - Enable Vulkan usage via the skia library (clang recommended)

Should it be renamed to "skia" for libreoffice, because that's also the
name of the upstream flag? libreoffice will also output a warning with
USE="vulkan -clang".

Right, this is a valid reason for enabling it.

IMHO this isn't. It is at least debatable if unpackaged proprietary
software should have any influence on our default settings.
