The reason is that I'd like to try out the new interface on IPcomp and make sure that it actually is able to do decompression piecemeal which is the main advantage over the existing interface for IPcomp where we allocate for the worst-case (64K vs average packet size of 1.5K). In that process we may have to tweak the interface.
