I think the reasoning is that it would be much nicer to have a compiler that runs locally so that you aren't dependent on Google to run the hardware even if they do EoL it.
It's a major issue for actual deployments of hardware in e.g. medical, education, research settings where a machine may end up supporting a piece of machinery for a couple decades on no support but just some spare duplicate parts that can be swapped in.
I once used a fiber optic splicer at MIT that was 2.5 decades old and ran DOS. Nobody gave a crap that it was DOS. We just needed fibers spliced and a new shiny touch screen splicer would cost $30K.
