No. I don’t think the smart patch tool works nondestructively. There are three nondestructive systems in Krita:
Alpha Masks. This lets you edit transparency for a given layer. A common use is to remove backgrounds. But you can also paint or use the gradient tool for soft transitions. Gimp has had this too since at least the 2.10 series. Perhaps 2.8.
Alpha masking of adjustments. This lets you paint or use the gradient on an adjustment layer, such as Curves or Levels. Again, to allow for soft transitions of adjustments. Note that GIMP 3.2 currently CANNOT do this. It does have adjustments, which are called ‘filters’ in GIMP speak. And like Krita, they can be reordered in an adjustment/filter stack. But unlike Krita (and Ps), an adjustment/filter currently only applies to an entire layer. The adjustment can not be edited within the layer itself on a mask.
Layer Styles. This is commonly used for nondestructively adding styles to text, like drop shadow, sparkle, glow, etc. Gimp got this in 3.0.
Gimp has made some real improvements with the 3.x series. But it still lacks basic functionality that Ps has had since 1997 with Photoshop 7.0, and Krita has had for something like fifteen years. But it’s getting there. And it does have better adjustments/filters than Krita. And it has had editing text on the canvas since 2.10 (I think?), whereas that’s being deployed for Krita 6.0 I believe.
