You answered the questions on exactly what is wrong with the console...
I am not making an argument against what you are saying. I am saying that a common interface between the two would be the sane and rational decision. It should be trivial to use the console and turn that back into your new behavior for committing back to your repository.
And it's pretty bad at this.
I'm not saying the interfaces are the worst ever invented, just that they are a step above internal enterprise software, and despite the fact that AWS makes almost 8 BILLION DOLLARS there appears to be less that 1/1000th of that revenue invested in improving it.
