Wrong. It is completely necessary. What happens if (a) the user
deletes the config file? (b) a different user runs the app? (c) a hard
drive melt-down wipes out all home directories, and the sysadmin
restores from last night's backup (which was before the app was
installed)? You MUST check for the absence of the user config file.
Most programs will be expected to function correctly after having
their configs wiped out - it's a standard way of saying "go back to
all defaults".
