There are more examples. A vignette of mine used a popular plotting package and some its standard examples -- which deploy mgcv::gam() to smooth, and of course without testing if mgcv was available. Which promptly blows up in a stringent CRAN test of vignette dependencies. Something used _unconditionally_ is not a Suggests.
