comment On a theorem of Kazhdan
Ah sorry, thought you were twisting by a character of the Levi (which would not affect the dimension... your current question makes a lot more sense).

comment Twisting of the power functor
Hi David, I mean the category of perfect modules over $T(k)$, which I think it's enough to consider as a DG algebra over $k$. (Correct me if this doesn't make sense).

comment When do limits and colimits of infinity-categories commute?
@Adeel Thanks, but neither of these is quite what I need. I need index diagrams that are more complicated than just products (so 5.5.8.11 isn't enough), and 5.3.3.3 is only about limits/colimits in the category of spaces (I need the category of stable infty-categories). However, there is something about my case that's not that far from the category of spaces, and I'm editing the question accordingly.

earlier statement was false. Salvaged it a little.

comment Components of a Fiber Product
Sorry! The fact that $f|_{I^n_X}$ is the identity on the first $r$ coordinates doesn't imply that its image is $I^r\times U$. (@user52824, the incorrect arguments I gave are in fact local).

comment Is there a finitely presented group with infinite homology over $\mathbb{Q}$?
Good to know. Thanks!
