Logged as #202 (https://github.com/latex3/svn-mirror/issues/202). I see
where the issue is: fix coming up. Is an 'urgent' release of expl3
required to deal with this?

BTW, I assume that the resize functions are useful. Do the current
interfaces make sense: they are down as 'experimental' but I do wonder
if they should get moved to 'stable'.
