Hello all,

Apologies for the slight delay on this: it slipped of my list. I have
now added \io(r|w)_new:(N|c) back into expl3. At present, these reserve
stream names but are not required, and so existing code will not break.
However, as it does seem appropriate to use these function, I will look
to make them required by \io(r|w)_open:Nn after a suitable delay. The
re-introduced functions will appear in the next CTAN snapshot of
l3kernel, probably by the weekend.
