I've sent a longish post to the R-devel mailing list with this topic here: https://stat.ethz.ch/pipermail/r-devel/2023-September/082892.html
In the mean time, the plan is to effectuate the change in R-devel (the in-development version of R) on Sep.28, ~ 9:30 CEST ( =UTC+2) AFAIK, this will only affect bioconductor packages *after* the upcoming release of BioC ... when they will all begin to run / be tested "against R-devel". But if you use CI / R-bug / rocker / ... tests for your packages using the development version of R, this may affect some of your bioconductor packages already sooner.
