Painting mounted on Fome-Cor

We recently acquired a Mexican painting, oil on canvas, 1798 that
had been in a private collection in Texas for the past few decades.
The former owner had had it conserved, and the at that time the
painting was "lined" to a 3/4-inch-thick piece of fome-core with an
unknown adhesive.

At present, everything is fine, but I am wondering about the future
stability of this marouflage combo.  How stable will the fome-core
be and for how long?  What problems should I watch out for?  Is this
technique common?  I've seen people use honey-comb panels made of
acid-free matboard as light- weight paintings support, but this is
my first encounter with a fome-core lining.
