Ideally we'd only maintain one of those, but I think your idea is good:
if we could increase verification by having an internal mechanism, this
would be an improvement. However, the question remains: what happens if
an attacker controls the website?

I'm not quite sure what you mean but we regularly and automatically
check that all the mirrors serve correct images ({IMG, ISO} + SIG are
checked), independently of the individual verification that users should
do when downloading an image. But there might be a delay with us
reacting to this if a mirror is compromised.
