tooltips can, depending on length, cause some issues for sighted users

To my knowledge no browser brings up a tooltip on focusable elements
when they're accessed via keyboard - and of course, if the title is on a
non-focusable element, then keyboard users wouldn't even get a chance to
get there in the first place (but your example of links is fine, of
course). So it really narrows it down to "sighted mouse (or rather,
generic pointing device) users". Interesting to also note that there's
no real hover on mobile devices either (at least not in the traditional
sense, unless authors explicitly work with the new, non-standard touch
events to simulate them).
