@neil While I would much prefer Google to clean out their own app store from all the malware that's already there, instead of hassling independent developers, I think that the "advanced flow" as shown in the linked blog post seems mostly reasonable. The one-day wait is only for the first time the flow is used, it doesn't apply on further installs or updates.

I would have expected worse (for example the user having to register with Google to bypass it, or there just being no bypass at all outside of ADB)
