Not an issue, you can swap line and neutral freely. It becomes an issue if you want to use three phases and a three phase motor (because the order of phases is important) but that is covered by other sockets. Plain old Schuko is one phase, LNG.
EDIT: thought about it some more, yeah, devices with switches on L may be pose a shock risk in some cases if you swap.
