Neither the MacTrast nor the original 9to5 article discusses the security behind Apple’s iOS implementation. But we know all firmware packages are signed and I would imagine this would be no different, with the recovery partition OS performing a check of the signature.
I’m sure Apple over-engineered the security of this to prevent this from becoming a vector for jailbreaking.
As a nice side effect, I would trust it.
Plus the people you would get firmware from like this would be your family/friends/coworkers or maybe an Apple Store employee if you really don’t know anyone else with an iPhone.
A pre-registered checksum will ensure that the downloaded file is what it says it is before running. So yes, it is safe. Unless you’ve found a collision in the checksum algorithm apple is using, although the chances are better that you’ll squeeze water out of dry desert sand.
(Edit: To those thinking they’ll rely on just code signing for this, you’re likely way off base.)
Is this safe?
Do I want to download my OS from someone nearby?

I assume it’s signed by Apple, so yes it’s safe. No, you don’t ever want to have to do this.
