Cleaner handling of multiple consecutive replies by the same user?

If your edit to the title plus this post reflect what you understood from the last time, I take it I couldn’t make myself clear at all.

It’s not about merging (it would be just a plus skippable feature) and it’s not about only me.

And I’m well aware of the warning for third consecutive reply.

I think I’ll just abandon this since I got no clue how to better explain this right now.
