This seems more trouble than it is worth!

That's actually been there for years. I understand that it works pretty well, although I've not seen/used it personally.

But doesn't it rather detract from part of the fun of cycling?

Well, yes perhaps. But it is more a utilitarian thing. If you're using your bicycle for transport, rather than recreation, it is more imprtant to make a trip faster or easier, than just "fun".
