So you mean, there is a security risk, luatex does not check its input and
arbitrary code can be executed?
The disadvantage of one cache per user is, that everybody needs to
regenerate the formats after an update, since the formats are also placed
(it was just a question out of curiosity, on my systems, there are no evil
users of course ;)
