After some delay, here is the final answer from ARM:

The change would require changes in firewall settings. We’ve discussed the issue with our Security team and unfortunately this change was rejected

So (we) either host the binaries else where or use a custom user agent when using tool.get.

Yes, lets leave this open for a while, so you can reference it too if you will try to raise it to arm.

If no further reports in a few weeks, then we will close it, thanks!
