Agree, post #23 is easier to remember

1- With Select by color, select the transparent areas;
2- With the Fuzzy select tool, in the Subtract from selection mode, select the external area;
3- New layer, Select - Grow =3, fill it with black;
4- On the initial layer, alpha for selection;
5- In the new layer, delete (Edit - clear).
I did try, and I messed the thing up
Result, shortening your method
1- With Select by color, select the transparent areas; (=> inside and outside is automatically selected)
2- With the Fuzzy select tool, in the Subtract from selection mode, select the external area; (this remove outside areas, keeping only the inner alpha selected)
3- New layer, Fill it with black (I drag and drop from the FG/BG icon). do not grow selection, just as it is.
Done!
Same gap as #23 => almost non existent.
Thanks to your last method, I just told myself if we don't grow we don't need to delete.
In the end I think we get over complicated, although it was very interesting to see so many methods and searching for the perfect pixel fit, but more I think about it, more I did forget the very basics as it can be as simple as:
1 Fuzzy the transparent inside (the inner alpha)
2 New layer => fill with black
