Yoshi nailed it. Nothing is designed for the most powerful link in the chain...rather the weakest (within reason). That said, I get the feeling that the <1gb mobile devices may have issues soon (that is not anything official, just a guess).
That that point it will continue to be an ever-moving target I would guess - older devices falling off, top end device users saying "I have the new 8gb phone, why can't you make it better for me". It's the curse of a game that loads everything into ram and that has been supported with free size able content updates (and still will be). Sorry to wax theoretical.
That said, The items you cited are not technical issues, they are issues with the current UI design. 505 Mobile already noted that a full UI revamp is in the plans (such would quite likely include adding those things).
