XChat's implementation doesn't have clickable links either. The only difference is the scroll and copyability. Scrollability seems useful for long topics, but copyability doesn't seem generally useful (unless you want to copy a URL, but you should really just be clicking those anyway).

All of this is mitigated by the fact that if you do want to (a) scroll or (b) copy, you can always double click the channel window or type /channel to see the full topic. In other words, it's there if you want it. There's an extra step, but just like XChat's UI, you have to click the topic line to be able to scroll to the end of it as well, so this is already an intentional UI choice. Double clicking doesn't seem that intrusive to me.

And if you want fewer keystrokes than even X-Chat, you can bind an f-key to display the full topic in your window:

Code:
/f9 //echo -a Channel topic: $chan(#).topic


If you ever want to see the full topic, simply put that in your aliases (Alt+R -> Aliases) and press F9. Not only will it wrap the full topic in your active window, but it will also make links clickable, which is already a step ahead of X-Chat. Arguably this would be equivalent to a "hideable" feature of what is being suggested.
