I believe the accounting our customers require needs to be turned on system-wide. In fact, I recall getting problems reports if there are some processes not 'accounted' for. If you do it on a task basis, and accounting gets turned on, you'd have to have a fool-proof way of tracking down all the tasks in a system and turn on their accounting. I would expect sites either want accounting on all the time for everything, or not at all.
