Jukka, No this is not considered, and you'll have to be really persuasive to make this happen as I do not see any advantage of adding this :) The reason is that in order to create e.g. the tile for level 0 for the first time, you'll have to downsample (and maybe previously seed) the full z=21 level (and all the intermediate ones).
