From what I can tell scrubbing only reads data and compares to the stored

If you have atimes enabled, reading a file also makes a metadata write. But
I don't think it's that big a deal on modern drives.
It depends on how the scrubbing works. I would have expected it to be
reading data at the filesystem level, not actually opening and reading
every file. That seems like a really bad thing to me, resetting the
atimes on every file.
