so we do - 35 servers running Fedora and keep up-to-date from F9 to F23 
while i do the development of the software running on top at the same 
time and one additional team member helps out

it does exactly what it is supposed to do and all is runnign perfectly 
fine as long not somebody breaks working things things by remove feautes 
for no good reason

most of that people are using LTS distributions where you don't have 
major jumps - it's enough to care about major upgrades itself and i 
don't need the burden "does config mgmt xyz support version a of 
serversoftware b"

for my own development not rely on any 3rd party libraries i can 
guarantee that there are no compatibility breaks and since that works 
now over nearly 15 years inclduing a complete jump from Apple to Fedora 
i am proven right

no, i don't say you or anybody else should do it the same way, do what 
you want, in the area where i am responsible i do the things which are 
proven to work with as less complexity and dependencies as possible

introducing another layer of complexity on a environment which works 
relieable and rock stable over many years and everybody who needs to 
touch it understands how and why things are working as they are supposed 
to do would be stupid

KISS - keep it simple stupid

well, you are talking about a no-problem since that file changed 3 times 
in 8 years where a hard restart of httpd is a no-brainer just because 
it's more often needed after PHP, zlib, pcre and what not updates
