Right. But that was something that was just changed recently. Because
one e5500 user complained about it.

It should. But it has been like that for ages and no one has
complained so far unlike with the ppc64 port. So I really think it
should stay that way. Most PowerPC machines are already underpowered,
so taking away Altivec on applications where it really makes a
difference would be suboptimal.
