[Cscwg-public] Code Signing Key Size changes

I'm not sure if everyone is aware that minimum key sizes are going to change


The Code Signing BRs specify that certs issued after Jan 1, 2021 must have
3072 RSA keys (vs the current 2048). This has been in there for a while, but
I fear that customers may not be prepared as it has not been well

In addition, making changes at the beginning of January is always risky due
to holidays, shutdowns, freezes, etc. 


I'm wondering if there is any appetite to move this to April or May 2021?
