Has the R core team publicly stated that they disagree with direction Wickham's Tidyverse is going? Genuinely asking as I love the Tidyverse, but would be interested to hear arguments against it.
I am not sure why the original commenter said that tidyverse is more backwards-compatible compared with R core. It used to introduce breaking changes every 6 months or so.
I like the tidyverse, but Hadley's struggles with lazy evaluation and arguments has cost me lots and lots of time updating internal code at various workplaces.
Don't get me wrong, the tidyverse is great, but if I was writing R code that I expected to run without supervision for a long time, I'd avoid it as much as possible.
Moving up to a major version (1.0) implies there could have been breaking changes if you follow semver. And including something like `unnest_legacy()` is helpful for people making the transition.
Just like `stringsAsFactors=FALSE` happened on a transition from 3.x to 4.x, because it is breaking, dplyr 1.0 had breaking changes.
