Epic Launcher @ DX9

Then I have some offtopic kind-of-philosophical question (will be happy if this will read some of UE4 developers). For what reason 2D tools exists in UE4? I mean, in 2D plays retro-fan guys, and guys that have old computers which can run only games from 200x and 2D games (which are still more powerful than Android devices, which UE4 supports, just another absurd). But what will happen when wave of 2D games come built with UE4 engine? What will be they thoughts? “What?? That time came?? My computer can’t even run 2D now?”
Ok, I know that in some statistics amount of users with DX9 is below 5%. But you don’t care who are these ‘5%’. I will tell you. I live in county where $35 considered as normal month salary. Yes, we have also prices for food 3 times lower than USA or Japan, but not for graphics cards, unfortunately. So lots of hardware here used more than 20 years, even at government institutions. What I’m trying to say is that these ‘5%’ is about 20% (and more) of gamers of such countries (some of them don’t have Steam, that’s because you don’t find such PCs @ their statistics). Progress is good, don’t get me wrong, but I don’t see the reason for which 2D must require DX11 and must not run on 5-10-15-years-old hardware.

P.S. I’d love to code in C++ with UE4, and I didn’t want to use Unity, I hate managed code, C#, .NET and other such things. But nevertheless, it still supports old hardware, and thanking for it, some kids in Africa still could play new games.
