if your tape is not back over the paper, then you'd might just as well not
tape it.

Son - in - law (ex to be) decided to do this old guy a favor and
drywall the cottage mud room. Left the plastering / mud to be. Only

feather out for the smooth finish. Any way to remediate this other
than rip it out?

Yes, there is. It's messy, but effective. Simply use a small angle
grinder and cut your own groove. Some screws/nails may have to be set
in different locations, obviously. Downside is the dust, so a good
shop vac is essential, and curtaining off the area. But you would do
some of that anyway for the joint work. It helps a ton to use a
Magnasand with the shop vac for dust control, and the screen sander
that comes with it makes the job really fly. Put a squirt of Pam non-
stick spray in the Magnasand trap to keep the foaming under control.
For a small room like yours the joint prep shouldn't take over 45
minutes or so. The final mud and sand will then be pretty quick
because you won't have to feather out a foot or so on each side.
The alternative is to just slop on the mud, feather out a bunch, sand,
mud, sand, etc. Or total rip out, as you noted. Your call, and good
luck.

I agree there is nothing wrong with just taping it and widening the mud a
bit.
However, I have, on occasion, done the following: Using a utility knive
(box
cutter type) I cut the surface paper at an angle away from the joint on
both
piece of drywall. Then, the paper can be pealed off. This give a
depression
for the new tape and mud. Not as messy as grinding!
