Allocating code points just means an implementation of draft-05 is likely to interoperate just fine with an implementation of the final RFC.

Of course nothing is ever final until the RFC is out, so there’s always a risk involved, but it is considered prudent to allocate numbers when we’re reasonably certain of the calculations and on-the-wire formats. Any debate about whether we should or should not check certain inputs for certain conditions need not be a bar for allocating numbers.
