How do I achieve a blur on an image texture (or any color output) with shader nodes?

I don't think there's any node that automatically blurs a texture (it would be nice, it would allow to easily tweak a height map from any picture), that said Decoded explains here how you can do it with this node setup: Plug your Texture Coordinate into a Noise Texture with Roughness at 1 and high Detail and Distortion, then plug into 2 Color > MixRGB, one in Subtract mode, the other in Add mode, and at last plug into your texture:
