Ze/hir are not widely used in British English, and are not used in the DWU except in the specific case of Sgloomi Po.

As for the specific question of "it" vs "they", I do not see a reason one should be used over the other. While a number of British English sources state singular they is technically improper, it has become common usage, and it is more preferred than "he" or "it" when discussing transsexuals/asexuals due to the connotations of "it" in this case. In cases of indeterminate gender, there are no such connotations, so "it" and "they" can both be used freely.

Direct quotations are, of course, to remain as is.
