Does someone know if bi-directional cross-filtering will appear in Power Pivot?

Just wanted to also say thank you for this feedback on such an important feature.

I totally understand if there will be differences between PBIX and XLSX, particularly on the visualization layer, but I'd hope that the data retrieval, shaping/transforms, and modeling features stay closely aligned such that it's easier to move between the tools and choose the right one for the given scenario.
