As feedback on the checklist:

It seems easier to do usethis::pr_init("rc/3.5.0") first, then do everything in the 1st block.
Also the cran-comments.md step should come after the revdepcheck results are in, I think.

+1 to the placement of cran-comment update. That's an oversight

The reason for the current setup with some tasks before veering off into a new branch is that it makes it much easier to merge the two branches together afterwards because new news items will be clearly separated from the one in the RC
