Thanks for the confirmation of my assertion that insurance is
shot if you operate outside the legal limits. Some didn't want to
believe it. Seems to me that the policy will have some statement to
the effect that any deliberate violation of the regs or manufacturer's
limits is sufficient cause for denial of compensation.

Interesting that insurance seems to be a stronger motivation than safety. The
reason such limits exist is to preserve safety, not to preserve insurance
coverage.
