Please accept my apologies. Indeed, the script [1] called at
configuration time does replace the examples section to avoid parse
errors for example(...). And having example() do nothing (with all code
and an explanation in the help page) is a small cost for having the
rest of the package work on R versions as old as 3.5.

I don't see a way to take this into account, since the workaround is
completely invisible to sufficiently new versions of R. It might be
that the best way forward is to revert the Rd example check.
