They do different things.
Deleting mutations marks each entry with a delete marker. Using the
iterator marks a whole row with a single mutation.
If you have a million entries in your row, the iterator is faster for
the delete, but requires a seek to the start of the row for every
read, so reads are slower.
If your row has one entry, they are the same thing.
Somewhere under N keys... the mutation path will be quite fast, and
still preserve your reading speed. I'll just pull a number out of
thin air... let's say a few thousand.
