There's no need to "rely" on it -- as you pointed out later, we could
use the checksum as the first signal, and then do a full content
comparison to make absolutely sure.

But before implementing this, we need some statistics on how much it
would actually save us. Are identical file contents common in
repositories? Have you done any experiments to find out? That's the
most important step here. If it turns out to be worthwhile, the
implementation of this optimization wouldn't be hard at all.
