I do multiple times a week, with repos that have barely been touched in a decade and all the original devs are gone. Squashing would make figuring out why something is the way it is a lot more painful, so I'm glad these repos are svn where squashing wasn't an option. Several times I've discovered bugs that were introduced in linting commits that would have been squashed, so the fix ends up trivial since the intention is already there in the previous commit.
