The ultimate stabilization is 'atomic wood', where you vacuum impregnate with a monomer,
then X-ray the stuff into plasticizing.
I use "cactus juice" for stabilizing wood. same idea with the vacuum,
but the curing occurs in a toaster oven at 200 deg F. Only problem is
the resin blisters a bit as it cures and cleaning this up on a bark
surface would take forever.

I've done several projects with bark left on the piece, without adding some
dedicated adhesive. As long as it's naturally secure enough, then the ad
dition of a finish, once dried and acting as a bit of glue, somewhat, helps
further secure the bark onto the wood. As long as the product/project is
not abused, when in use, then the bark will stay in place. Here's an examp

Update - Scrolling right from the pic above, the next pic shows the edges a
re square. Yesterday, I rounded those edges (the pic above). Finish sandi
ng of these edges is next. Both of these pics are dry fitted.... nothing
is yet glued. The rounding of the edges were done with a flexible disk sa
nder... 24 grit, then 36 grit, then 80 grit. Buffing around/along/onto t
he bark did not loosen the bark from the wood. So your scenario may depen
d on how your finished product will be used.
Similarly as with this rocker, the large walnut table (some years ago) has
some bark remaining on some of the edges. That bark is still securely in p
lace. It is naturally adhered fairly well and the addition of the finish,
at least to a small extent, adds to that adhesiveness.
More rocker update: I got some of the backrest and seat slats cut out. St
ill need to pull the lumber and make the rockers. Hopefully I can start so
me gluing next week.
