I would consider this the sysadmin's fault for letting logs grow without
bounds. Surely you have heard of log rotation?

If you have debugged your code well, and got rid of all the
E_WARNING/E_NOTICE that you can, then surely you would want to know if a
new one crops up? I see no problem with having E_WARNING/E_NOTICE enabled=
.

E_DEPRECATED is another thing though. Enabling this by default is good
because you will notice when code you are using becomes deprecated.
However it probably shouldn't be enabled in production as you should be
upgrading PHP on a development/testing/staging system before you do so
on a live server!
