Especially for such large sparse VMAs, the current way of allocating

IMHO that's not a generic workload. As mentioned in the reply there, I
would suggest we go with simple then we have space to optimize it in the
future if necessary, because the API will be the same.
I disagree with "generic workload", we use sparse mmaps all over the
place, and when blindly used by e.g., CRIU, we'll simply end up wasting
memory and time.
But I already agreed that this optimization that is a separate thing to
implement.
