I think that's what Jeff meant, yes.

(Basically, can authors already solve the problems that
"vector-effect:fixed-position" is intended to solve, by simply creating
two different <svg> elements (in an HTML context), and styling one with
"position: fixed">?  Here's a simple demo with a floating fixed-position
legend, using that sort of solution:
https://jsfiddle.net/vv9gwemr/
)

Also, Jeff asked another important question -- have other browsers
expressed any intent to implement these features?

Also note that this feature is marked as "at-risk" of being dropped from
this version of the SVG2 spec:
"ISSUE 31: Values of vector-effect other than non-scaling-stroke and
none are at risk of being dropped from SVG 2 due to a lack of
implementations."
https://svgwg.org/svg2-draft/coords.html#issue31

Looks like that warning was added here:
https://github.com/w3c/svgwg/issues/186

If no other browsers are intending to implement it, then there's a
serious question of whether it's worth taking on this added code & the
increased complexity/attack-surface/bug-surface/maintenance-burden that
new features inevitably bring along, if web developers aren't going to
be able to use the feature on the web due to lack of support in other
browsers.
