My take on the eight outlined points.


 * 1) No more than 100 worlds.
 * 2) Fanon xenos species should have, at most, a technology level comparable to that of the Imperium of Man during the Great Crusade or the Tau Empire during the Third Phase of Expansion. Under no circumstances should a race ever be as technologically adept as the Eldar or the Necrons
 * 3) Simply put, no. So far they have been amongst some of the worst written, most broken and poorly developed articles on the site. It breeds lazy "telling not showing" writing and generally breaks the setting as they either attempt to be Tyranids 2.0 or The Mighty Multi Galactic Empire of Doom.
 * 4) See above (ie. No).
 * 5) Races of xenos should be limited to being, at most, as psychically adept as the Nicassar. If you don't know what they are, you probably shouldn't be making a xenos species in the first places. Typically they should be more akin to human psychic potential.
 * 6) I cringe at the term"Immunity to Chaos". Particularly given how insidious Chaos is, to the extent that daemon flesh has been melded to a psychic blank before. Arguably every race, save for the Necrons, could theoretically be corrupted in some shape or form.
 * 7) All blank races simply shouldn't be. The point of the C'tan (in 3rd Edition Lore) putting the Pariah Gene into humanity was as a last ditch attempt of breeding warriors capable of standing up the predominant psyker populations of the galaxy. As this is now a canonical grey area as well, all blank races should not exist. At the most, a race should have a minimal warp presence like the Tau.
 * 8) If the race died in the War in Heaven I don't see a problem. If they didn't, it tends to fall into the trap of being a cheap "explain away the origins" gimmick. One that even Games Workshop has fallen into. While not NCF per se, it is a overused plot device.
