The SVG change to `<number-percentage>` was made to match similar changes for CSS Colors 4, which was made to be more intuitive for authors; the decision to switch to [`<alpha-value>`](https://drafts.csswg.org/css-color-4/#typedef-alpha-value) is likewise just about consistency.

I don't know if any browsers have pushed implementations for percentage alpha in any property. I would hope that it would be pushed out uniformly for all related properties and also for alpha colors.

You'd need to skim through https://github.com/w3c/web-platform-tests/tree/master/css/css-color to see if there are tests for percentage opacity in colors and the opacity property.

You'd need to consult implementers and the Colors 4 editors to decide whether this is really a stable change that we should be pushing now, with expectation of implementation this year, or if it should be deferred to future spec levels.
