Think about this:

outline:solid (as a 2d filter) can be represented by
a pulse-shape function.

Meaning of outline-offset and outline-width for such
a function is exactly what I use for outline:glow.

"Radii" of outline:solid (outline-box bounds) is a sum
of outline-offset and outline-width.

To be short, I did not change meanings of outline properties.

And yet:
outline:glow and outline:dotted are used for an indication of
visual(:hover) and input(:focus) states in UI of various OSes.
