Indeed, having such a feature in-game does make the puzzle redundant - but this is exactly what people who use Alt1 want. On the other hand, there are people who see it as outright cheating, therefore it should be banned.
Jagex are therefore in the difficult position of either banning it's usage completely, or accepting it's usage by providing it to all. Either option is going to cause upset.
I suppose another alternative is to remove puzzle steps completely and replace them with something that cannot be automated/done in mere seconds... something like "chop 50 logs" or kill 3 bosses". I wonder what would be harder to implement *thinking emoji*.
