The extra braces on L32 and L59 are just so variables for any number of kinds don't have to come up with unique names. Is there a better fix for this, or can we live with the extra braces?
I tend to think the only real fix could be that the kinds were iterated here in .go instead of in the template but there is a reason they are iterated over in the template: on this side, they are packages which are way harder to iterate over.
Could always spit more files to make individual
ManagedKindfor each of the groupversion and then simply import here though.
