Uhm... excuse me? Why? Is there anyone even using DOS for anything serious these days?
Most computers in Turkey come with FreeDOS preinstalled because there's a law that states all computers must be sold with an operating system. FreeDOS turns out to be the cheapest and easiest.
That's why you don't let people who have never touched a computer write tech laws. You get results like this.
Who said anything about "serious"?
(FWIW: I suspect there are more than a few old industrial control systems and such out there that are still running DOS, just because of an "if it ain't broke, don't fix it" attitude)

Because it's fun, at least for certain folks? Crazy, right?
There used to be stock exchanges running happily on DOS. Maybe there still are.
There are several reasons. One possible reason is, if you do not need the functions of other operating systems, then DOS will be much simpler.
It's a simple enough implementation that implicitly helps document how SDL is supposed to work (DOS being a well understood platform by now). Plenty of reasons to maintain it based on that alone.
There's a lot of interesting projects and even innovation going on making new games for old PCs/consoles. James Lambert and Kaze are doing fantastic work in the N64 space as one example (watch their videos on Youtube)
SDL is written in C. So it can support it without too much trouble. And some people are compiling stuff to run on DOS. So it makes sense. And your objection doesn't hold any water.
because you can
Because computers can be used to do things that are not...so serious?

Translation: "Stop liking things I don't like!"
Perhaps not serious, but I think people gravitate towards older systems these days because they are easier to conceptualize. It's not unrealistic for a single person to have a complete grasp of e.g. the C64 and it's programming environment. DOS is similarly constraint, but also easier for you to form a more or less complete mental model around.
Some people love computers and making them do weird stuff, older computers make certain tasks feel more manageable.
