Eh… why? More to the point, it’s not mentioned anywhere in their guidelines, it was made up on the spot by the fella doing the code review.
They are inefficient and bloated.
And personally, I prefer good reasoning over good rules. If something comes up that is a bad idea but there’s no existing rule against it, the rules should be changed to address it. As long as the reasoning is sound, I think it’s a good thing, especially when we’re talking about something like a software distribution platform as opposed to say laws that determine freedom or imprisonment.
Also if you’ve made a web app, let it be installed as a web app. Both FF and Chrome let you install web apps in one click.
Inefficient and bloated describes 90% of all apps I’ve ever seen, regardless of technology used, so I fail to see your point.
