Summary

Remove the hasExtension() methods on SVGAnimationElement, SVGCursorElement, SVGGraphicsElement, SVGMaskElement and SVGPatternElement.


Motivation

These were in SVG 1.1 but have been removed from the spec. They always return false and usage is basically zero.


Compatibility Risk

Insignificant.

Alternative implementation suggestion for web developers

Assume that hasExtension() always return true and simplify the code accordingly.


Usage information from UseCounter

Usage is zero for all of them.

Requesting approval to remove too?

Yes.
