That's typically true for 99% of bundle purchases, that's not a digiphile thing.

Not everyone is aware of that, hence why I mentioned it. It's worth stating because Digiphile (among other retailers like buying from the IndieGala store) specifically state that the keys you purchase are region-locked to the country you buy them from, which is BS.

It's awesome that you are aware of it not being true, but not everyone even here on this site knows that.

And again... I would take your second advice with a massive heap of salt. If a key is expired, you should be wary of all unused keys to be revoked at anytime, not assuming "they're perfectly fine"

This is sort of a mischaracterization of what I said. Some keys will be perfectly fine, while some keys devs/publishers will manually revoke in Steamworks once they don't have a further obligation to make them valid for redeeming. That was what I said.

You said "If a key is expired, you should be wary" but the point I was trying to get across in the first place in what I said was that this doesn't actually happen, keys don't actually expire in that exact way even if a retailer tells you they do (assuming of course that you have revealed the key and have it in-hand). I thought it was worth mentioning as this is another common misconception, that it's much better to leave keys unrevealed and that when the "expiration date" (not really) passes you are out of luck almost all the time. But in reality even from Humble many "expired" keys are activating just fine these days. And to reiterate, I just thought that was something worth mentioning as I'm pretty sure it's not super well-known. But indeed some will be revoked.
