If I perform brushing/masking in PS are those edits still editable/reversible. Maybe.! If I need to do a lot of cloning, spot removal, Heal Brush, work, then it has to be Photoshop. In Ps you can create a new empty layer above the background and set the tool option to "Current and Below" so that all the re-touching work is on its own layer (or multiple layers) that you can re-edit (in Ps). BUT only if you save the (PSD, TIFF) file to PRESERVE the layers. You will see the image in the Lr library, but 'Preserving the layers' in the file means- never doing any further edits in Lightroom, and always re-opening the file in Photoshop (Edit-In) with the option "Open Original" Note: The reason to "Open Original" is: If you do edit the file saved from Ps with further Lr Develop module adjustments, opening this adjusted image will flatten the layers and all the Ps layer information is lost. Hence the reason why many experts & gurus, recommend that do as much as possible in Lightroom and then Edit-In Photoshop as the last step in the editing workflow.
