Sounds like an argument for Apple to provide a new high-level media import framework?

Why? A new framework gets you new bugs instead of the old ones, but not necessarily fewer or less severe ones.

It’s more likely that things will be reversed: the old, battle-tested framework may have bugs, but it’s is less likely to have serious ones.

They should try to hunt down bugs in the existing code. A partial rewrite of parts that historically have many bugs may be in order, but a complete replacement? Unlikely to be an improvement.
