There is an unofficial minecraft console edition speedrun page not endorsed by the admins here. Some of those categories may exist there, however I belive you are allowed to submit any platform runs here and it will be next to your name hence you could still be the fastest on that platform whilst submitting them here,

To my knowledge there is very little documentation or programs to help speedrunning on other platforms although some runs could be theoretically faster on those platforms. Most runs are slower. So submit them here and you should be fine, the same rules would still apply however.

this already exist because you can already submit a run under console.
