That's also a sign they aren't comfortable with the version control system. I used to be like that, and with cvs and svn it was somewhat justifiable. Now that we have git and it's everywhere I'm far less anxious. Not that git is perfect and things don't happen, but it's extremely good at not Screwing Up. It may not do exactly what you expected, but it doesn't break the repo. It also tries really hard to never forget anything unless you make an effort to force it. It might take a bit of digging around in the reflog to figure out how to get back to a sane state, but in every case I've had to deal with it was possible.
