because, I think:
OFX imports match via complex heuristics(*)
OFX imports have a FITID field which is stored in a transaction split's
invisible "online_id" property.
QIF imports don't have a similar field, so, the matching is actually done
manually during every import, and is imperfect(**)

(*) matching tests: amounts match, make some allowances for ATM fee
threshold, dates differ by ideally 4 days but consider up to 2 weeks.
(**) matching is successful when: amounts matched, dates differ by 1 week
or less.
