I think it's OK for schemas to be mandatory for programs, but problems
start when the program has several optional modules or plugins with
each having their own schemas, and the main program does not require
any of those optional modules to meaningfully work. So g_settings_new
unconditionally aborting might not be a bug, but it is very
inconvenient for the programmer.

I think the following could be done to fix this problem:
a) provide a function called g_settings_schema_exists that would check
whether creation of GSettings for a given schema name would succeed
b) provide g_settings_try_new as suggested before
