    //      This value represents the total *outstanding* GHO principal that was originally minted and backed by the old GHO AToken
    //      facilitator mechanism and is currently borrowed by users. Here's its derivation:
    //        a) In `UpgradePayloadMainnet` (step 2), `levelFromOldFacilitator` was fetched. This `level` was the net GHO
    //           minted by the old GHO AToken facilitator that is still outstanding (i.e., not yet repaid by users and subsequently burned by the facilitator mechanism),
    //           effectively representing the total *currently outstanding* GHO principal borrowed by users under that original facilitation mechanism.
    //        b) In `UpgradePayloadMainnet` (step 6), the new `FACILITATOR` (GhoDirectMinter) minted GHO equal to this
    //           `levelFromOldFacilitator` and supplied it to the Pool, receiving an equivalent amount of GHO ATokens (`aGHO`).
    //        c) These `aGHO` tokens are now held by the `FACILITATOR`, and their `scaledTotalSupply` (assuming GHO liquidity
    //           index is 1 RAY) equals `levelFromOldFacilitator`.
    //      Thus, `ghoPrincipalComponent` accurately reflects the total principal portion of the *currently outstanding* GHO debt.
    //
    uint256 vTokenTotalSupply = IERC20(ghoReserveData.variableDebtTokenAddress).totalSupply();
    uint256 ghoPrincipalComponent = IScaledBalanceToken(AaveV3EthereumAssets.GHO_A_TOKEN).scaledTotalSupply();

    // Calculation for `accruedToTreasury`:
    //   Total Outstanding GHO Debt (vTokenTotalSupply) = (Total Outstanding GHO Principal Borrowed by Users) + (Total Accrued GHO Interest on Outstanding Principal)
    //   GHO Principal Component (ghoPrincipalComponent) = (Total Outstanding GHO Principal Borrowed by Users)
    //
    //   Therefore: `accruedToTreasury` = `vTokenTotalSupply` - `ghoPrincipalComponent`
    //                                 = (Total Accrued GHO Interest on Outstanding Principal).
    //
    // This calculation assumes GHO's liquidity index is effectively 1 RAY (1e27). If the index is 1 RAY,
    // `scaledTotalSupply()` of GHO AToken directly represents the actual GHO token amount for the principal.
    // The 100% reserve factor for GHO helps maintain this stable index.
