you are correct. why add the complexity of a specialized plugin that can take years to work the bugs out of. it all comes down to being super focused and diligent whenever you edit anything on a complex model. maybe also 'saving a copy as' at the end of each session so you can step back in time to see when the problem was created and re-build from there.
And also please note that Skin only works:
only works with curves:-> to make it work with lines: divide them and then Weld them.

only works with curves that are not contiguously:
