But for Plasma 5 only alternative I can think of is using ColorOverlay/Colorize from QtGraphicalEffects but the results don't look very good, icons and text get blurry and it supposedly has a performance impact.
Additionally that would make the implementations diverge and will make maintenance of both versions more difficult and I would like to just focus on the latest Plasma version.
For those reasons the plasma 5 port won't be maintained anymore.
It seems the ability to override icon colors is only available in plasma 6 https://github.com/KDE/ksvg/commit/50c5716d3b532debe6878723dcb92e740746b3ea
