Absolutely nothing about this project or the way they went about building it shows any tendency towards richer tooling. A web interface also does not inherently enable richer tooling. You could implement this non-line oriented protocol entirely without 500+ MB of JS and the interpretation of that data could obviously be done without it too.
Edit:
While I understand your rants all over these threads (it doesn't inherently have to be inefficient and bloated), you've picked a strange submission to take these fights in. The software in question is in fact bloated, not compliant and is really only an interface to aliases.
Also, I would add: The proof is in the pudding. You seem to have made this a personal crusade, so I would urge you to make a decent PoC with these ideas to show the world.
