That is a good point- we can look back on our collection of fics and see our progress. That's probably a major reason I like putting them on AO3 or SW- it's like my library. I'm a bit of an obsessive re-editor, I go back every so often and make a few changes. Like chiselling at a sculpture.

Yes, things that make us stop and re-read paragraphs to work out what is going on, are not good are they 😕
