Maintaining such a table is pretty useless unfortunately since result tables already exist (made with 'non fake' SD cards) and since a huge amount of people really think they could buy a recommended SD card that costs $25 normally on Aliexpress for $8 instead.

Then they end up with a fake card with less capacity/performance/reliability but it's hard to convince them that they bought crap. That's the reason why we added to our user documentation two links how to check for bad cards, two links how to choose a better one (already containing your link from above) and in the meantime an own utility to check SD cards even if they're already in use.

I respectfully disagree. The provided information with links to amazon is helpful.
Sure you will have variations between units of same type, but that table gives you a ballpark figure ( and with the crowdsourcing effort may contain more information than the link provided above).
Given that not everyone has gazillion of cards lying around to test and know what to choose, and granted that some of those cards are in same price range but offer drastically different performance having that information does help.
And about aliexpress - there are things to buy there, and things to avoid. Knowing the counterfeit market of usb sticks / memory cards I would use more trusted ( non-marketplace) vendors.
