> As a consumer, would you want the extra usage on your battery?
I feel like this is likely going to be a non-issue in practice. Because these batteries are rated to last at least 10 years either way. And by that time, the cost of replacement will be dramatically cheaper.

They are rated to last at least 10 years (under X usage conditions)
They won't last nearly that long under Y usage conditions if Y is substantially larger than X
