Its actually a pretty Good use of CGI, this whole Scene seems to look very good, seems to done it Justice, its a shame some of the Xenomorph and Neomorph CGI appeared to be lacking... It had the same kind of look like THE THING 2011 where towards the end of the movie the CGI just appeared more inferior compared to early on.
Certainly also gives us a good look into the Black Goo, it now appears the Substance Invades a Host and then Replicates/Mutates inside some of the Cells of the Engineers, Cells as in Fluid Cells so like Blood etc... and then inside the Pathogen just keeps reproducing over and over until it escapes from the Engineers.
You could certainly imagine this kind of Reaction inside of a Engineers Space Jockey Suit, would eventually try and explode out of the Suit, and thus cause those Holes we saw in the Engineer Suits in Prometheus.
The Problem is the Prometheus Engineer Suits appeared to be Hollow, as though the Engineers just broke down to nothing, like the Sacrificial Engineer (apart from the Head of the one Engineer)
While in Alien Covenant the remains of the Engineers look like Stone Statues, Pompeii like in appearance.
Which is why i Pondered could a SAFETY device had been activated to release a Engineer Blast that Destroyed all Organic Mater within a Radius including the Black Goo, as a means to prevent it from spreading by in effect turning all ORGANIC matter to Solid Crystallized Stone.
Looking at this Video of what the Bombardment was doing, i now think this THEORY i had prior to seeing the movie could actually be plausible because i fail to see from this Scene in the movie when looking at the break down video.... i cant see how this leads to those Engineer Bodies ending up how they was discovered.
