I think that it's clear that installing the package that way is
potentially unsafe (well, when you know what module may crash, you
don't risk much), is tricky and just a workaround. At the time there
was no insider package that fixes it, there was no alternative but this
hack. I personally faced no issue at all w/ that workaround and am
waiting for the next stable to jump in, I consider the insider one as
less reliable.
