Uh, no. Data loss for your end-users as a default behavior is unforgivable. The impetus is on people who think it's OK to irretrievably lose access to their freaking data when their phone battery explodes to set that up. For myself, and for Joe P. Random, losing my data without my having explicitly (and again) decided to take that risk is what directly precedes a decision to no longer use any Google products, full stop.
