That’s fine as long as it’s open source and a self-contained local piece of software (as Fuchsia is). The problem with Google killing products is that they’re closed source and/or require huge server resources and/or ML models.
But those write-ups were years ago and there hasn't been new reviews with much UI focus since then.
There is now a UI experience available as part of Fuchsia in the workstation product, but I wouldn't overly index on it as it's just one take on what you could use Fuchsia to build.
