So? The fact still remains, regardless of personal opinion about Adobe, Lightroom, & Photoshop, those using that software have the ability to maintain a fully non-destructive, and reversible workflow, that includes reversing the effects of any filter including USM.

It's not a "reversible" workflow. The correct terms would be either a non-linear undo, or simply that it can be reverted.

the correct term and the one used by everyone except you is a non-destructible workflow.

âEUR¦and if you are going to start that reverse mathematical operation from a compressed, & lossy JPEG, good luck getting back to where you started.

Floyd L. Davidson
Your workflow, even if non-destructive, will be totally unable to deal with reverting any previous editing with the exception of processes, such as sharpen (not USM), that are reversible.

nospam
wrong.

in a non-destructible workflow, *everything* can be altered, adjusted or removed at any time, including unsharp mask, cropping and retouching.

you've clearly never used such a workflow and are talking out your butt.
