The best remark is actually in his previous article, which he mentions but doesn’t link, Let’s have some sympathy for the part-time R user. Emphasis mine:
There is a temptation that if you are going to only teach one system it might as well be
rlang/tidyevalas “that is what now comes with
dplyr”. I feel this is a false savings as while
rlang/tidyeval“is already in
rlang/tidyevalconcepts and details are not “already in the user” (and in fact include a fairly number of irregular exceptions, needing to be taught and memorized).
