Why remove this one? It does no harm. If it plays bad with new tooltips - that's
a good sign that we should improve something so all possible tooltips are
pleasant to use.

Again there is no added value here and is more likely to get in your way. This
abuses the tooltip UI construct. We want tooltips to always be useful so users
will learn to discover detail there. If its always used for echoing content
already there, this effort would be in vain.
