Hi Simon,
Thanks for the long and thoughtful and detailed reply. Just 'sitting back' will do just fine then. R releases annually in April, the 4.2.* series was just fine. We had an usual event in that R Core upstream asked (a first in ~25 years) to patch 4.2.2, hence the somewhat unusual version name 4.2.2.202211110 in bookworm, it otherwise is just 4.2.2. The delta to the final release in there series, 4.2.3, is small and either is fine but we can live very well with the version that got to bookworm 'naturally'. 4.3.0 is a new one, as annual releases go the delta is also pretty small. But it can and will just wait in unstable til its time is up post bookwork release. The CRAN repo upstream is very very good about ensuring consistency 'at @HEAD' so package are generally in good shape (especially if they are kept current). I expect no surprises here.
