Spicy Scions Soup

Am I reading this right?

A) The Tempestor Prime makes Scions battleline units

B) There don't seem to be any other restrictions for Tempestus lists

Does this mean we can finally field tanks and infantry squads and ordnance batteries? I mean, I can't be the only one who painted all of his regular guard models in Kappic Eagles colors all this time... That would make Tempestus a lot more versatile, interesting and also possibly really fluffy!

(I'm aware we technically could soup with IG in 9th edition as well, but the detachment rules made it so needlessly complicated.)
