It's probably too late, but I'm quite sure that the removal of
\tl_new:Nn, \ior_new:N and \iow_new:N should be reverted. It is
universally considered good style to combine declaration and
initialization of variables, and having two different commands for
declaration and setting leads to awkward duplication. Regarding
\io[rw]_new, without them it is is impossible to check for overwriting
of stream names. Just like with all other variable types, these should
be declared before usage.
Also a \cs_new:N command is missing which reserves a "function" name
without assigning it. Both \io[rw]_new:N and \cs_new:N can essentially
be aliases for \chk_if_free_cs.
