If you look at the MNSW proof carefully, the base case can be taken to be the trivial fact that a $0$-round protocol for $\textrm{GT}_n$ with $n = 1$ requires one bit of communication.
If the goal is simply to convince oneself from first principles that $\textrm{R}^\to(\textrm{GT}_n) = \Omega(n)$, this is immediate by reduction from the AUGMENTED-INDEX ...

I don't know about a survey, but I've found a recent PhD thesis, which seems to be well written:
Heinlein, Matthias (2019): Erdős-Pósa properties. Open Access Repositorium der Universität Ulm. Dissertation. http://dx.doi.org/10.18725/OPARU-11828
The first chapter gives a summary of the problem, known proof techniques and provides references to recent ...

The Ph.D. thesis of Pranab Sen (http://www.tcs.tifr.res.in/~pgdsen/pages/phdthesis/thesis.pdf) provides a $\Omega(n^{1/t}t^{-2})$ lower bound for $t$ round bounded error CC for Greater-than. I think the proof covers the case when $t=1$.
In addition, there is a $\Omega(n^{1/t}t^{-3})$ for quantum CC in the same thesis.

I met once a similar notion to what you want in one paper by Mark Zhandry's paper under the name $k$-wise equivalent. I cannot find further references or pointers from that paper, but I think this name nicely describes your something.
Concretely, the original definition in the paper is about the distributions over the functions $f: X\rightarrow Y$, and ...

Here is an example exploiting positivity of an index to prove false:
module Whatever where
open import Level using (Level)
open import Relation.Binary.PropositionalEquality
open import Data.Empty
variable
ℓ : Level
A B : Set ℓ
data _≅_ (A : Set ℓ) : Set ℓ → Set ℓ where
trefl : A ≅ A
Subst : (P : Set ℓ → Set ℓ) → A ≅ B → P A → P B
Subst P trefl PA = ...
