Anyone else feel that client proofing should be better than it is in Lightroom Classic?

I've always had issues going back and forth with clients on proofing — Lightroom's own Web Gallery never quite cut it for this, so I'd end up just sending a folder of images, they reply "I love these three, hate that one, and can we lighten this one up a bit," then I'm cross-referencing that back into Lightroom by hand.

Built a plugin that fixes it for myself: it generates a self-contained HTML gallery straight from Lightroom, the client stars favorites and leaves notes right in it, sends back a small file, and it re-imports the ratings/notes straight into LR.

Cleaned it up enough that I put it up for sale (ProofingGallery, $29.95 one-time, not a subscription — enginecollective.studio/proofinggallery) but honestly just want to know if it's useful outside my own workflow. I've got 2-3 free licenses if anyone's interested in trying it out and sharing their thoughts.
