Instead of just asking why someone is not here, why not making a well explained suggestion why that someone should be here in your opinion.
I didn't know John Hackett would have a prog rock [-related] discography, other than classically oriented collaborations with Steve, and other classical music recordings, as one would expect from a flautist. Unfortunately All Music Guide, in which John Hackett and his albums are included, doesn't give much information...
EDIT (see below): " There is no need for any reasoned argument as he obviously should be on the site"
Just tried to remind how things work here.
