This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The <feMerge> SVG element allows filter effects to be applied concurrently instead of sequentially. This is achieved by other filters storing their output via the result attribute and then accessing it in a <feMergeNode> child.
Like other filter primitives, it handles color components in the linearRGB color space by default. You can use color-interpolation-filters to use sRGB instead.
