Is there such a thing as a FREE program which has the Photoshop feature of "lasso around a mold and press Delete to remove it" feature?

Adobe Photoshop has this feature, introduced a few years ago, which I don’t understand how I ever could live without:

1. You lasso-select an area, such as a birthmark or mold.
2. You press the Delete button.
3. It fills in the mold intelligently with surrounding data, making it "magically disappear".

Of course, this has always been possible by smudging in the surroundings into the mold/defect, or by "cloning" nearby parts over it. Both with Photoshop itself and other programs. However, this is much more involved and annoying, and in practice, it rarely looks as good as this tool makes it look. At least not for me, without significant effort.

Ever since I dropped Photoshop forever (subscription nonsense, spying/bloat/annoyances, etc.) and started using Krita, I’ve been missing this feature.

Is Krita planning to get this soon? Or is there any other (freeware) software that can do this one task? It’s truly a killer feature, and it wouldn’t surprise me if Adobe paid some really juicy salaries to extremely smart programmers to implement it…
