This is a good point - as you say, I agree we can omit the creation of
the lock file. It would be good to double-check how it behaves when you
have a format where you have one filter for reading, and other one for
writing ;-) But either way, I don't think that actually creating the
lock even though the filter is import-only is that serious issue, ie.
you can remove the locking of the file later, it is not blocking your

No idea, without testing myself. I think we could fallback to
autosaving in ODF format, if we do not do it yet ;-)

I'd still prefer not to set the read-only flag if possible, it is a
terribly annoying feature [see the other threads about read-only mode].
