The worlds may be 'limitless' but Minecraft itself isn't. At least, not imaginably so. At some point you have to stop and say 'Done.'
Otherwise you eventually leave an unfinished painting. I'd personally love to see Minecraft reach 10.0 by the time I stop playing. But by such a high number, we may be screaming Too Many Items to put on Too Many Items. Realistically they need to stop at 2.0 or 2.5, say let's do this, and make a Workshop for mods and enhancements.
