I believe that LilyPond's behavior is correct. From the Scribus bug discussion referenced above, Scribus administrator jghali says:
"However both SVG 1.1 and CSS 2 specs tells us the the default value of 'color' is 'user agent defined', ie implementation defined. So the result of using 'currentColor' before specifying explicitly a value for 'color' will be implementation defined. Given that this svg from lillypond does not specify a 'color' value before using 'currentColor', I have to consider that lillypond is relying on undefined behavior and hence this is up to Lillypond to stop relying on such undefined behavior."
When Scribus imports an SVG file, Scribus is acting as a user agent. The user agent is the renderer of the image, not the creator of the image. Scribus has modified their default currentColor to black, to match the standard of web browsers. IMO, this is the correct thing to do.
By using currentColor instead of black, I can easily use CSS to display my LilyPond music output as SVG in any color I wish.
I don't believe LilyPond's behavior should change.

instead of "black".References:
https://bugs.scribus.net/view.php?id=15454Here is a quote from a Scribus forum snr. member:
"the lillypond authors seem to know about the issue but (probably) wrongly
decided to do nothing...can somebody who uses lillypond try to post a bug report for this issue with
jean's explanation from the bug tracker and telling them that this shortcut
makes hard to import the svg in scribus?
(i mean, they could keep track of the color used and always set it
explicitly, instead of relying on a default value that seems not to be 100%
standardized)."
