Its not really ad hominem, Android itself us a massive pile of hacks (zygote process, project treble, binder, etc) that while it worked for google in fixing their issues it is far from ideal. Also what API has replaced FCGI and CGI in general? Hopefully not in process modules.
What's replaced it is running services or application servers that contain an embedded HTTP handler, and putting a load balancer in front of it.
Also, rather than guilt by association (Android et al, which was done under different circumstances compared with the hundreds of other libraries Google has released), why not actually hear out the concrete proposal and then criticize it?
Saying no one in category X can ever build anything good is just illogical.
