Well, it must have some reason that the international standard 230 V household

That thing has ONLY been planned for adoption by BRAZIL!

You say "international standard", but the part of that that makes it
"international" is the fact that an international organization published
it. Other than that, it is quite obscure.

There are many reasons for choosing round or flat contacts. There are
many connector systems... many different connector system designs.

One factor is temperature.
