It sounds absurd but ... you too will find it perfectly normal once you have
done it a few times :)

Seriously: this can (and does) happen with binary interfaces.  On Windows,
CRAN rebuilds _every_ dependencies whenever a package changes.  We do get by
with something more robust on macOS / Linux most of the time. But not always.

And some R version changes actually mandate it for packages with src/
directories. R 3.5.0 is one of them.  So it was not "your fault" or "bloody
Rcpp's fault" but quite possibly simply par for the course.

And you're up and running now so all is good.
