The reason why I registered them is that they are used by Firefox and there was
the possibility that the PPID based fragmentation and reassembly got
standardised. I wanted to avoid the case that Firefox uses some values
and other protocols register these values. That would have been pretty
bad. Since they are a very cheap resource, I just went ahead and "saved"
the values.
