They would. That is why I 1) test on a test account that I fill with
fake mails and where I delete/read a bit through the webinterface to
make changes on the IMAP side.

Once I am a bit more certain that there are no grave bugs eating my
mails, I backup my maildir, so I can reupload everything in case it
deletes stuff. The worst thing that could happen is silently throwing
away *some* of my mails without me noticing. That's why I don't run the
test code on my work account, I use the installed last stable
offlineimap for that.

Having a test suite could increase our trust that it behaves well, but I
am still not sure how it should be done best.
