The security bugs which led to the conversion ban are fixed for a long time.
So it would make sense to file a bug in ubuntu that the permanent ban makes
lyx unusable for standard vector graphics formats. Moreover since /etc is writeable
only for root, normal users has no chance to override this restriction with their
own policy files.
They might listen to us or not, but it's IMHO worth of trying.

"convert -list policy" and if not trigger message that those conversions were
banned. The combative part in me would even add note which would suggest users
to file bug to their distro maintainers so they get some additional feedback.
Maybe if they close the same bug 100x times they try to do something about it ;)
