All of this has happened before with 'AR' for television. The eventual niche was just a few election/budget politics shows rather than day-to-day broadcasting. A few things that were hard to do with 'AR' for television - getting feet to stay consistently on the ground in the one place and not float or drift with camera moves. The reality of solving this was to use a close up shot where the feet were not shown or to pan very carefully with a camera on a tripod.

It is these finer technical points that stop the technology getting too far and prevent you doing really cool stuff with 'AR'. This of course does not matter if it is some effect on Snapchat, however, if you really are trying to get someone to appear as if they really are 'walking on the moon' then sliding feet makes the result look like bad chromakeying and not the 'AR' desired.
