It would have been interesting to see a line drawn at maximum racquet headsize allowed at, say, 95''. Such a regulation should emphasize control, feel and attacking tennis rather than sheer power and gets in absurdum in the game.
What I do think is that the game's authorities have been lax over equipment regulation and basically ceded control of this area over to the manufacturers, allowing them to build whatever they want and call it a tennis racquet as long as it's within certain guidelines, which are probably too loosely drawn.
That genie was let out of the bottle decades ago and there's no sign of it slowing down - the style of the game has changed even in the last ten years, spin rules now.
The manufacturers keep going and who knows what developments they will come up with next and what the game will look like ten years from now. It's something I hope the tennis authorities have belatedly become awake to and are keeping a close eye on the situation, though I suspect not.
