Just wow. I assumed that Google patched this few years back but guess they left a few backdoors.

It's probably an oversight than a "backdoor". They already have a "frontdoor" in the form of a permission that's pre-granted to them by the OS, so there's little need for them to devise backdoors like the android.intent.action.MAIN query that the blog post mentions.
