Toward SM Tide game:
The thing with people suggesting (or asking/demanding SM game, is that yes those game would work, SM are quite flexible lorewise so could be made to work for quite a lot of different style of game.
But even in the last 5 years (and taking out any card games), 40k has got 5 SM led game (with a new one coming)
On the other hand, the Inquisition has 2.5 (Inquisitor Martyr/Prophecy and DT); Rogue Trader have 1 (Eponyme), Mechanicus has 1 and will get a new one, as for Xenos, only Orks have some and they have 3 (Speed Freeks, Shootas and Dakka Squadron.
Like if you look at this suggestion we’re just echoing to the problem that the TT had not so long ago (and still somewhat has) where SM fans would alway get an equal attention cake
