Can't define Default method for kinds watched by multiple controllers #483
Description
My manager installs multiple controllers for the same kind. If I define a Default() method for that kind, I get an error on startup:

Presumably this is due to

I may be doing something wrong, as the webhook stuff seems mostly undocumented and I'm just trying to figure it out by picking through code.
