There is a new Nest audio device out which apparently has good audio and is at the same price as Homepod Mini.
Even with Nest specifically they dropped Works With Nest support last year, effectively killing off the many integrations that had been built since 2014 in favor of their newer Works with Google Assistant program.

But I agree with you.. they're generally better about hardware support than software.
The "Nest" rebrand of the Google Home devices to me signifies that they're really investing in this consumer IoT product line. That and they're (arguably) the dominant player in the space.
Nexus Player still works though.
