Excellent idea, thank you! It does work for R CMD check as well:

Sys.setenv("_R_CHECK_S3_METHODS_SHOW_POSSIBLE_ISSUES_" = 'TRUE')
tools::checkS3methods(dir = '.') # used to show esa.plot as well
# Apparent methods for exported generics not registered:
#   fxi.contour fxi.mode

No need for extra bits or attributes on the esa.plot function, just
register a method for "esa" generic, "plot" class to prevent S3
dispatch from reaching the function in question.
