Apple to Clean Up App Store, Eliminate Outdated and Non-Functional Apps
Apple today notified developers about some upcoming changes to the App Store, which are designed to make it easier for customers to find high-quality...

Going via the above link, Apple stated removing apps from app store (I reckon 2013 and below) as would be "outdated"
However, it makes no sense in leaving alone "purchased apps" where all Apple is concerned with are "users will freak out if they are not listed only" regardless of whether they actually work or not.. which is kind of a silly approach from Apple's perspective to take.
This tells me Apple has two separate Databases and copies of each, as if the item is removed from the store, why can i still download if they were linked ?
For eg.. allot of games on the App sore my purchase list are from 2013... Doom 3,, Cal of Duty 4 etc...
I haven't tried all of them yet.. but Doom 3 fails on Mojave... it "partially" works (which is probably why Apple treats these different), but fails after the intro screen, so i can only assume similar for others from this era...
Is there any way to get these to run on Mojave? as going by the relevant forums clearly state they will run.. Not Mojave specific, but in relation to Catalina is mentioned "These games will still work if you don't upgrade" etc.. However, i will question that.
