That would actually be practical for naming years in the current century, e.g. twenty hundred nineteen for the current year sounds much better to my (Dutch) ear

That would actually be practical for naming years in the current century, e.g. twenty hundred nineteen for the current year sounds much better to my (Dutch) ears than two thousand nineteen. We do say twenty nineteen, of course, but the intermediate "full name" step of twenty hundred nineteen is never used, making it a bit weird.
