We’ll certainly take a look at that.

Right now we still have unallocated address space, both in 103/8 and in the reclaimed/reserved pool. So there can still be still bogons.

We will continue to reclaim address space from closed members, and perhaps we will be able to reclaim some of the unused address space in APNIC ranges. When we do that, we always reserve the reclaimed space for some time, before reallocating it. This is precisely to ensure that the space is not being announced (which would be a bogon), or subject to other blacklisting or quality issues.
So, bogons can exist in future, any time that a currently unallocated address block appears in the routing table. But whether ISPs will filter them is another question.
