Exactly, at least in theory; if the closer clearance has grown by 'x' then the opener will have shrunk by 'x' although each needs to be measured individually as there are other variables.
If you're planning on doing your own maintenance and keeping the bike then it's definitely worth buying a shim kit from EMS in the USA;
