Probably not quite as bad as IPv4, but, potentially close.
In theory, yes, it's bad.In practice, the RIRs are implementing sparse allocation which makes it possible to aggregate subsequent allocations. I.e. not as bad as it may seem.
ARIN, RIPE and AfriNIC, for example, allocate on /29 boundaries. So if you get an initial allocation of /32, then find you need more, your subsequent allocations will be taken from the same /29, allowing aggregation up to /29.
APNIC seem to be delegating on /22 boundaries, and LACNIC on /28. Nick
