I don't see a problem leaving a gap that \write16, \write17,
\write18 or other special \write registers aren't effected by
the write register allocation. The allocation code just need
to know, how to reliable test whether additional writes are
available. For exmaple, e-TeX version number, if it would be
part of e-TeX. Or a new primitive for this purpose.

Yours sincerely
