The same could be said for any ffmpeg CLI command line string, which
people happily share on the web all the time, it can also contain
multiple output files which can get overwritten without question even
with the right commands.
Should we remove support for writing those files as well? :)

Ultimately, multimedia processing has to write files at some point. If
people copy-paste commands without understanding them or even worse
give people access to command lines without control, trhere is nothing
we can really do to protect them.
