It's an anti-competitive concern all the time.

If we gatekeep service access to specific implementation attestations, it becomes much harder for new implementations to emerge. It doesn't really matter who controls the process.

In that sense, it's always bad. In this specific scenario for example it directly blocks emergence of alternative Android ROMs and Android-mostly-compatible devices like the various Linux phones.

There may be times where that downside is worthwhile, but it's always a downside, and we should very strongly discourage attestation wherever possible on that basis for the health of both the tech ecosystem and the business market around it.
