That's not too unreasonable.
I don't think it is necessary but I don't think it is objectionable.

Yes - those require patching though even if put in /var/www.
Config files should never be in the web app root for security reasons.
With php - I know you can make a php includes directory that php can see
what apache can't. That's what I do for things like database passwords
etc.

The /var/something is important also for security reasons - especially
with SELinux.

Try to get those patches upstream, as upstream is broken in those cases.
Where to put log files and cache etc. should be in the configuration
file and not in the web app code itself.

-=-

I personally don't do a lot with web applications (I did in a former
job) - but maybe we need a web app SIG to come to a consensus on how
they should be done, and submit docs to FESCO for approval or rejection,
so that people packaging them can have somewhere to look.
