Ah right; I missed that because I chopped it off when quoting you!  Sorry.

Yes, that seems better...

...although there will be plenty of things that can't compute to 
flex-item, including table, grid, flexbox.  So the problem will still 
exist for those.

I guess I'm just not sure whether half doing something is better than 
not doing it at all.

Either way, I think I would like to see a note in the spec explaining 
that the computed 'display' of table, grid etc when these types are flex 
items will change from being 'table', 'grid' to being 'flex-item table', 
'flex-item grid' in future.  (And hence it's best not to code anything 
that relies on those values.)  Hmm, perhaps introducing 'flex-item', 
albeit partially, would underline that point.
