There are two intrinsic problems as I understand it. 1) The glass will
delaminate from the wood, one way or another. 2) Moisture will get into
the wood from the inside and the wood will stay wet and rot (because the
bottom is sealed).

I have never had any delamination or wet rot problems as you
described.

I had a homebuilt plywood 26' sailboat covered with glass that was 25
years old when I sold it with absolutely no problems.

I have lived aboard my 1961 40' sailboat for the last 7 years. Strip
planked mahogany glassed over. The glass and wood are both in perfect
condition on this 43 year old boat.

Both of these boats inner hulls were never painted and stay bone dry.
On the occasion where I had a rainwater leak, ect. and got water in
the hulls, after the bilge pump removes the standing water the rest
just evaporates away.

Note that both of these boats were glassed when they were newly built.
