What is known about the theory

($\ast$) ZF + "every Suslin set of reals is ${\bf \Sigma}^1_2$"?

By "reals" I mean elements of the Baire space $\omega^\omega$. For a cardinal $\kappa$, a set of reals is called $\kappa$-*Suslin* if it is the projection of a closed subset of $\omega^\omega \times \kappa^\omega$, and *Suslin* if it is $\kappa$-Suslin for some well-ordered cardinal $\kappa$.

Shoenfield proved the converse: assuming ZF, every ${\bf \Sigma}^1_2$ set of reals is Suslin (and in particular is $\aleph_1$-Suslin.) Every wellordered set of reals $A$ is Suslin (and in particular is $\left|A\right|$-Suslin) so the theory ($\ast$) is inconsistent with AC.

I was able to show that ($\ast$) is consistent relative to ZFC + "there is a generic Vopěnka cardinal," where the definition of "generic Vopěnka cardinal" is obtained by weakening the definition of "Vopěnka cardinal" to allow the elementary embeddings between structures to exist in a generic extension of V, rather than in V itself. (See Bagaria, Gitman, and Schindler [1] for the analogous variant of Vopěnka's principle.) As is typical of such "virtual large cardinal" properties, generic Vopěnka cardinals are between weakly compact cardinals and $0^\sharp$ in terms of consistency strength.

Moreover, I showed that ($\ast$) + "$\Theta = \aleph_2$" is equiconsistent with ZFC + "there is a generic Vopěnka cardinal", where $\Theta$ is the least ordinal that is not a surjective image of the reals. (So in ZFC, the statement $\Theta = \aleph_2$ would be equivalent to CH.)

I have two historical questions and one mathematical question:

Has the theory ($\ast$) been considered before?

Was any consistency strength upper bound for ($\ast$) already known?

Can we obtain any nontrivial consistency strength lower bound (i.e., better than ZF itself) for ($\ast$)?

A couple of facts are worth mentioning here:

(A). Martin and Solovay proved that ZFC + MA + $\neg$CH + "$\aleph_1^L = \aleph_1$" implies that every $\aleph_1$-Suslin set of reals is ${\bf \Sigma}^1_2$.

(B). ZF + "$\Theta = \aleph_2$" implies that every Suslin set of reals is $\aleph_1$-Suslin, but this hypothesis is inconsistent with the hypothesis of Martin and Solovay.
