Option to have a "Scarce" and a "Plenty" option at world creation

Good day,

One thing that striked me as being interesting is allowing players to have more direct user-friendly options in regard to world generation tweaks - as I seem to understand it's do-able via modding but built-in options are always better.

At the moment, we essentially only get options between a few tweaks relative to the world generation (such as structure spawning world option or the world Type ie : Superflat or Large Biomes)

I would suggest implementing an option to change the quantity and density of ore veins - possibly ore by ore (for exemple - but could also be applied to mob spawning I guess ?).

I'm not quite sure how hard it would be to implement but it feels to me like it would be a neat option for all players (experienced players could generate their worlds with scarcer ressources whilst, more casual folks could enjoy having more and bigger veins)

(I wasn't quite sure as to which category to fit this in, if it's out of place, I do apologize)
