The question is, do we want this? Do we really want to support what these chips are doing to the spectrum? The mentioned Baofengs (or variants of them) for example are already banned in Germany [1] and Switzerland [2] due to their piss poor output harmonics filtering. If you look closely, even more reputable radios like Anytone blast out awful harmonics.

And IMHO that's a fundamental, unavoidable problem with the design of these chips. You can't just go and do everything on a single IC with barely any passives for filtering.

And that's ignoring the question if they actually got a proper license for the vocoder - AMBE is still under patent protection until end of this year AFAIK. Honestly I'd be surprised if they did, but it's yet another thing to be aware of when importing these chips...
