I've not noted it down, but I think the reason I went for just 'total
height' functions here is that the end result then has a dimension (or
dimensions) that are explicit in the code. Something like

    \box_resize_to_ht:Nn

gives you a box that is not necessarily the vertical size you've put
into your code, which could be regarded as a bit odd. (It's also doable
by viewing this operation as a scaling to ht_new/ht_old.) Of course,
this might just be me: one reason these are in the 'candidates' part of
l3kernel is they've not been discussed a lot, so some feedback is almost
certainly required.
