I would hate for kissing / splanking to go away entirely, but in their current form they are pretty annoying. When they happen you can't interact with the game for a while after they occur (via mouse, if you use a keyboard you can) and as the game grows this might become more and more a problem.
I would love for those actions to be a box that happened in the upper right corner, like a little growl but bigger, and with the same visual animation in it. Something that doesn't become a full takeover, but at the same time something more than just text.
