[R-pkg-devel] Is S3 class registration essential for CRAN?

[S Ellison]

A short question: How necessary is explicit S3 class registration for CRAN submission? 
R-forge's check is giving me a note on this for a handful of methods in a package, and I'm unclear whether it is something that _needs_  to be fixed for CRAN submission by registering all S3 methods, needs to be fixed for _some_, or doesn't need to be changed (the present version on cran is running without apparent issues, but was submitted before the checks expanded to pick this up).
