LTC3553 floating STBY

Hi All,

I've made a batch of devices using LTC3553 as a power controller (pushbutton, LDO and LiPo charger are used). Some time ago I suddenly found out that due to a mistake when tracing the STBY pin of the LTC3553 left floating. This is forbidden by the datasheet, but it is not explained why.
I understand that this must b fixed, but most of the batch has already found it's way to customers and it's impossible to repair.
What are the expected (or unexpected) consequences could have a floating STBY pin?
Thanks in advance for any hint!
