Self disassembly's pretty unreasonable.
There was an in-depth analysis commissioned on the Mosquito prototype's airframe a few years ago and there's no structural reason why it couldn't fly.
Admittedly the earlier adhesives did fail, but only in tropical service. There were no problems with the later system.
Despite later epoxies being superior, it's a deviation from the original design so needs Design Authority and mountains of paperwork. The same problem arises when trying to substitute linen covering with modern fabrics.
