Cool! I’d forgotten until now, but I had that exact idea back in the stone age, 10 or 15 years ago, and started working on it but got bogged down. It was clearly feasible but a huge amount of work, too much to justify the cost. So it’s a perfect job for coding agents now. Nice one!
I do you think now need to watch out for the opposite problem. These things become so easy to build that the temptation is just to go ahead and build. But unless you really do need them, all that new code just goes to waste. The cost to produce has become very low, but sometimes the value can end up being negative.
