Some time ago now, we removed a number of functions which it had become clear did not quite 'fit'. One of those was \tl_new:Nn - use either \tl_new:N plus \tl_set:Nn for a variable or \tl_const:Nn for a constant. Functions for removal are now announced on the list both when we decide to remove them and when we actually do. A comprehensive list of functions removed since the 'big bang' work (which moved expl3 into 'l3kernel') is available from https://github.com/latex3/svn-mirror/blob/master/l3kernel/l3obsolete.txt We anticipate that very few functions will be removed from the l3kernel in future, but there are still some places where this may happen. AS I said, we are aiming to announce /every/ removal on the list. -- Joseph Wright
