Plaster walls and ceilings from the 20's would most likely be wood lathe.
After many years, the plaster squished between the lathe,(keys), falls off,
and the plaster looses much integrity and cracks and falls off. Papering
over it helps to keep it intact, and I'm sure you can patch and repaper to
keep it looking decent. Ideally, removing the plaster and lathe and
installing sheetrock would be a good solution, or sometimes you can have a
3/8" layer of sheetrock installed over the plaster.

....

OTOH, I've worked on refurbishment projects of many houses from the
_18_20's where the plaster is still in excellent condition. For a
plaster job of less than 100 years to be in that bad of shape implies
it wasn't very good to begin with.

As someone else noted, impossible to say much from the information
provided for a particular case. Personally, I'd be prone to keeping
the existing plaster and repairing it unless there's far more evidence
than a few spots here or there.

I also agree w/ the assessment it's far better to go to the trouble of
removing the wallpaper down to a solid surface and then make the
decision of whether to paint or re-paper. If going to the effort to
begin with, really can't see the point of not doing it right to begin
with.

No way to answer that question. In my previous house (built 1943), the
plaster was a mess. Lot of cracking and separation from the lath (the wood
strips underneath). In my current house (built 1956), the plaster is all
perfect. I recently converted a single electrical outlet to a double, which
involved enlarging the hole in the wall. It didn't look like the lath or
plaster were different from the previous house, so I suspect the difference
might be chalked up to the fact that this house settled differently.

The real question is whether or not you like the wallpaper. Fixing plaster
isn't so hard. It's time consuming, but that's about it. As Colbyt said,
drywall mud works nicely for fine cracks, or skim-coating a whole wall to
eliminate texture you don't like.

If the plaster is cracking and pulling away from the wall, is soft,
crumbling etc. then the chance of wallpaper helping is about 0.00001%.

It is really difficult to make general statements as each case is
different. It all depends on just how bad the original plaster is.
