It is well known.

it's not well known, as it's a fairly recent addition to the spec and
only recent wifi radios support it.

FSVSVO "recent", unless you consider 5 years to be "recent".

wifi is ~20 years old, so yes, and its still not widely adopted yet
including android, which will be in 'o', a system that doesn't even
have an official name.
