Calling something a "hack" implies that the developers took another game's programming and used it to make their game. Unlicensed games, for all that can be said about their quality, are usually built from the ground up with engines the developers programmed themselves, even if just to mimic another game. To use an example already on the site,
Squirrel King for the Genesis is an unlicensed knock-off of Capcom's
Rescue Rangers games, but it is not a hack; the games they are copying were only ever released for the NES, so the developers programmed their own version of the engine from scratch. The infamous Genesis
Super Mario World, on the other hand, qualifies as a hack; it is an edit of
Squirrel King which replaces the knockoff Chip and Dale with the Mario Brothers and the first stage with World 1-1. This
Jurassic Park game, crappy as it is, looks to have been made from scratch, not based off of any other game, and is therefore not a hack.
The movie itself seems to be technically sound; the TAS player executes a shortcut flawlessly and is able to grab all of the eggs using what looks like the shortest path. Therefore, I say "Yes" to publishing this run in the Vault.
