  I'm desperately trying to resolve all of our dockershim uses so we can migrate to EKS 1.24+, but I'm not optimistic I'll get it done before the "deadline".
  
  I'm stuck on EKS 1.23 until I can replace DooD. I wonder what will happen when it's no longer supported in October?

  so you should do it yourself to keep control. Otherwise it could happen any time after the EOL date.
  
  They also state why they do it like that:
