policy for scp copying files

I’ve script which makes automatic upgrades of my devices.
Now I want to make upgrade to R-OS 6.35.2 and I found one bug. For copying files to R-OS device by scp is required policy “ftp”.
Previous version of R-OS which I use was 6.32.4, where for this action policy ftp wasn’t required.
IMHO necessity of ftp policy for scp is wrong.

We found the same problem.

We use scp to copy configuration backups off the router.

Ideally there would be a way to generate a backup and scp it off from a read only account.
