See https://rebench.stefan-marr.de/som-rs/, commit df5215, which should be "frame functions now take a Gc<Method> instead of a Gc<MethodOrPrim>" but prints "frame functions now take a Gc<> instead of a Gc<>"
In commit 9986e1, it seems "Option<NonNull" got turned into "Option>" also.
Doesn't bother me much, but for all I know this removed expression could be interpretable, so reporting it for security reasons
