Perhaps I missed this part, but is "port to PHP 8-preview" or "port to JIT" 
even a thing?  Presumably, just like with 7.0, any reasonably well-behaved 
application would be able to run without modification or with only minor 
modification on 8.0, no?

I mean, if someone wanted to try out their massive application to see if the 
JIT helped it, why would it be more work than (psuedocode):

git clone myapp.git
cd myapp
docker run php8-preview
*open web browser*
