Given the specificity of the providers they list, they are probably using their APIs instead of IMAP, which is a lot easier.

Or they've just whitelisted said providers after having either verified that providers IMAP implementations comply with IMAP standards, or they've whitelisted said providers because those providers were big enough that it was worth the trouble for Google to work around issues with those providers IMAP implementations.
