In sys v initscript it started out as variable options, placed on top 
for administrator ease of changeability then due the share size and 
complexity of the sys v initscript it evolved it into environment files 
which led to file location based fragmentation between distribution ( 
and is now hindering share-ability of type unit files between 
distributions ) but never through all those decades did someone go and 
fix the underlying problem which is as you point out lack of daemon 
reading configuration file.

The same pattern has started to re-emerge in a form of an workaround in 
systemd by using drop-ins containing [Service] Environment= or 
EnviromentFile=, which I suspect they are doing based on his description 
either themselves or they have administrators do that to overwrite those 
entry's since they generate that metadata file ( which is more likely )
