VPC network interfaces - hot, warm and cold attach

in flag

According to Best practices for configuring network interfaces guide, there are three ways to attach a network interface to an instance:

You can attach a network interface to an instance when:

  1. it's running (hot attach),
  2. when it's stopped (warm attach), or
  3. when the instance is being launched (cold attach).

However, the only places where these terms are mentioned is the AWS documentation page linked above, some SAA-C03 practice exam questions at Cloud Guru and exam notes published at personal blogs.

Are these terms really a thing?

If so, using the word "warm" for attaching to a stopped instance and "cold" for one being launched seems to be counter-intuitive. Why such a choice of words?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
