I don't think there is no commonly accepted "natural sort". For
example, I found another one that uses the same order as the python
one that I showed above. The so-called version sort in corutils' sort
is just not natural sort and it should not be called natural sort.

$ printf '%s\n' G . | csvtk sort -k 1:N
G
.
$ printf '%s\n' 1G 1. | csvtk sort -k 1:N
1G
1.
$ printf '%s\n' 1G13 1.02 | csvtk sort -k 1:N
1G13
1.02

Wikipedia also explains what natural sort is and provided a few
implementation links. I don't think any of them implemented the
version sort as the natural sort.

I don't understand this sentence. There is an implementation with just
a few lines in python. Unless this implementation is wrong, then there
is a simple implementation at least in python.
