Hello,

During testing I did not observed any issues with the old value. So I am 
not sure how the switch is affected by the incorrect setting.

Maybe maintainers will be able to make a better assessment if this needs 
back-porting. And I will be happy to do it if it is necessary.

Best regards,
Razvan
