  I understand. It's a clever design. I'm just pointing
out that in that scenario there's still the lossy
original JPG and there's still loss in the final save.
So if one is going to work with JPGs then it seems a
good design.

  I think we're saying the same thing. You work in
RAW or TIF, then export to JPG only if necessary. I'm just
pointing out that it makes sense to store in non-lossy
formats in the first place, either RAW or something
like TIF, when it comes out of RAW. And if
it's coming from JPG? Why not convert it anyway?
That's basically what LR is doing -- saving some
kind of backup bitmap image. By saving in TIF you
can cut out the middleman and don't need to be
limited to LR. And you can also have multiple edits
as multiple non-lossy files. Like "beach.tif",
"beach without uncle fred.tif", "beach2.tif",
"beach3.tif", etc. And any of those can be worked
on further. Maybe that's not relevant to you. I
like to save whatever I do as a non-lossy file, in
case I later want to proceed from that point to
do something else.

   But it's true that I don't use LR. I just use the
basic computer file system. If you prefer to have
LR keep track of your images then letting it handle
bitmap backups may be convenient.
