Entryway has that dark early 1970's paneling.

I've finally decided to get rid of it, so I did a little exploratory
surgery to see what kind of a project it will be.

The good news is the paneling isn't glued to the drywall. It'll come
right out.

The bad news is there is no drywall. Someone put up homasote board
underneath the paneling.

Is this common?

It is common as interior walls which will be covered with a more durable
surface.
Its value is that it is more soundproof and has more R value than sheetrock.
What do you intend to have as a finished surface?

I usually just take the cover off a light switch to see what the
backing material is. Our 1958 Chicago suburb house has 1/2" sheetrock
covered with 1/2" plaster for all walls, the extra plaster makes a
huge difference/improvement/loss in sound transference. Outer walls
are the same on the inside side, plywood with tarpaper under cedar
shingles for the outside walls. Only problem is the occasional
woodpecker.
