I think folks are drastically missing the forest for the trees here. This is just one minor example of the INSANE process that is now the Chrome Approval Process. I've seen extensions go for many months getting random rejections with no reason given. This forces developers to GUESS as to what is wrong. Want to try and develop according to a roadmap or timeline- forget about it. There is no "app store" approval proces…
After 2nd to 3rd rejection if it will require a human to intervene Google will have to hire half the earthlings to deal with crappy spammers that will simply spam google store with their extensions. The answer is not human interaction, the answer is automation tool to give more details as what was detected and didn't pass.
And then Google will have to hire half the earthlings to write all the special-case code into the automation tool...
