Aria spec is nearly 20 years old, with the first drafts being out in 2006. Labelledby was a core part of the first spec, and is not particularly complicated. There is no way to make a change to title attribute that isn't breaking to some use cases if you want it to support everything label/labelledby supports. That said, if you are talking about tooltips, which are different from accessibility attributes, I digress. Tooltips have always been a software nightmare, and the web is no exception.
