I'm not sure if here by sandbox and break you mean break the
cabal/package installation, or protect against malicious code.

If it's not the latter (and even if it is, how safe are the sandboxes?),
I would argue that until cabal can verify authenticity of downloaded
archives, it would be better to not do this automatically. Maybe add a
new command, cabal fetch-deps or something like that, that can do it,
but leave 'cabal build' as a "safe" command.
