it behaves badly, large chunks of CRT over a 20f radius, at least on the rectangle. I have not witnessed a roundie implode. on and the rectangle let go after a somewhat "difficult" attempt at the removal of the bonded lens.

I am sure the bonding agent is a good idea, but not cheap, a while back I looked in to optically clear PVB (think that is what it was) that cures from exposure to UV, VERY expensive. I would think it has to be a non air dry type of bonding or it could take forever to cure.
a more practical solution would be to steel strap the CRT but, again I have no idea of the details on how to accomplish that. I suppose the roundies are less of an issue on the need for some kind of implosion protection, but that is just a guess.
