Sorry, I missed this remark.  meson-buildoptions.json is not 
hand-written.  It is the result of Meson's own parsing meson_options.txt 
exported as JSON.

In the commit message "because we parse command-line options before 
meson is available, the introspection output is stored in the source 
tree.  This is the reason for the unattractive diffstat; the number of 
JSON lines added is higher than the number of configure lines removed. 
Of course the latter are code that must be maintained manually and the 
former is not".
