I think that in some cases, the multiple finals are at least semi-ironic. For my fiction writing, I number each draft with -dn at the end of the name and leave it at that. I will occasionally have modified versions of that when it goes out on submission (most commonly -d5-anon for journals that require anonymous submissions, or -d5-journal for journals that have idiosyncratic formatting requirements (some journals want the cover letter included with the story, some want single or 1½ spacing, one asks for a brief note on the creative process at the end).
