The email discusses the distinction between anchor channels and non-anchor channels in relation to fee bumping and spending outputs.

This implies that Replace-by-fee (RBF) and Child-pays-for-parent (CPFP) mechanisms are not relevant in anchor channels. The email also includes a link to the website https://petertodd.org, presumably for further reference on the topic.
