remote snapshot backups just continue to collect indefinitely?

I see we have the option for how many 'local' snapshots to keep. That's good.

But there is no option on how many remote snapshots to keep?

So will they just stack up forever and I will have to manually remove them from cloud storage if I don't want to eventually fill it up with thousands or millions of zip files?

Also would it be feasible to add an option to make a single sql dump file instead of or as well as the separate table sql files?
