Hello Derek,
Using the tweak is not the same as disabling/removing the cameras from the image set. For example, the depth maps would be generated considering all the possible neighbors (may be useful for the depth maps based mesh reconstruction).
In the version 1.5.3 build 8432 we have set the default value for main/dense_cloud_max_neighbors parameter equal to 100, so it should considerably reduce the processing time for the dataset with the excessive overlap, but shouldn't affect the quality of the results for the common datasets.
