Yes, very true. But there already *is* a threshold today
<>. If your language needs twice
as many characters as another, today that just means that you're twice as
likely to have the tooltip disappear before you've read its contents.

So yes, the problem you point out exists, but I don't see how what I propose
makes it worse. On the contrary, being more clear about what is meant with
"short" and "long" makes it easier for authors and UA implementors to auhor
and implement @alt better.
