Hmm, I think this is device/vendor specific, I have slots with card edge completely hidden, sticks out a bit, sticks out a little but under additional cover and even sticks out more or less significantly, like Cisco makes it. Actually it is possible to pull the card out "manually" in the latter case (but why someone would bother to do that while having handy ejector?)

If you're looking for an external device where the "card" is fully enclosed, that role has been taken over by swappable SSD. Your use case basically doesn't exist anymore (except in the wishes of Canon camera users).

Not really this, my case specifically is to have "desktop" style card reader which doesn't trade convenience for smaller size, so I don't have to grab the reader to carefully pull the card out, just push the button and take the card.
