A Simulator of a Universal Turing Machine (2017)

Not a fault per se I guess, but I wonder why people do things like that. To me it'd be like using an aircraft carrier to go shopping, or something. And yes, I realize there's no real cost in requiring a C++ compiler but ignoring 99% (or whatever) of the language's capabilities, but it looks weird to me. :)
I guess on this scenario a lot of people would take their carriers to shopping too.
There, you’ll find several Turing Machine simulators including at least one that runs online: http://morphett.info/turing/turing.html

Considering it's over a size 8 alphabet, that amounts to 5361 bits (over 26 times longer than a self interpreter for a simple functional machine model https://tromp.github.io/cl/cl.html)
Minsky is more famous for his 7 state 4 symbol universal Turing machine, whose universality is far less direct as it simulates a tag system. I wonder how big a tag system that machine translates to, when trying to feed it to itself.
I was hoping it might include a compiler that converts code from a higher level language into the language of the Turing Machine, but sadly that doesn't seem to be the case. That means the example programs are all hand written, though, which is quite impressive.
