One might also note that parallel:: detectCores() itself says not to use it this way!
"This is not suitable for use directly for the mc.cores argument of mclapply nor specifying the number of cores in make cluster"

The detectCores() apocalypse is creeping up on us 👻🐛
As more people are getting access to 128+ CPU cores, code spinning up parallel cluster with detectCores() workers fails - not enough #RStats connections available
Friends, do *not* default to detectCores(), bc www.jottr.org/2022/12/05/a...

Please Avoid detectCores() in your R Packages
The detectCores() function of the parallel package is probably one of the most used functions when it comes to setting the number of parallel workers to use in R. In this blog post, I’ll try to explai...

For other #RStats pkg devs: don't forget to upgrade your old .Deprecated() warnings to .Defunct() errors.
I just grep:ed my code and found overdue ones in 'progressr' & 'listenv'. With .Defunct() in place, I'm one step closer to be able completely remove two fcns from these packages 🧹
