Is the concern privilege escalation in build recipes in malicious elpa

But couldn't the same package run the same bad code at package install
time on the end user's machine, today and for as long as elpa.gnu.org
has existed?

Ie, if we assume malicious code can get into elpa packages with no-one
noticing, the whole system is already broken anyway?

So would it be good enough in practice to avoid accidental damage by
running make as a dedicated elpa-build user with no special privs?

But if you want to make the elpa system more secure one piece at a time,
that's obviously no bad thing.
