It can be implemented well but often isn't. Likely eID will force you to use an mobile app (no website or Linux app, yay) that is only available on Apple's app store or GPlay. And if you want to run a degoogled android ROM good luck with that when they force Play Integrity. Basically shoving everyone into either the Apple or Google walled garden along with the complementary spyware of both gardens and also screwing anyone who uses a non-smart phone either out of choice or circumstance.

Perhaps worse than the 9 when it comes to wifi which has been downgraded from 7 to 6e. Will most users care? Maybe not, but I do.
