I may add two cents on that as we recently made this change in data.table. Using markdown package instead of rmarkdown as a vignette engine reduced burden caused by extra dependencies tremendously. Moreover it made package to not even need c++ compiler, as knitr and markdown both (and their recursive deps) are pure C with no C++. Gains were huge. Deps installation time from 12min to 30sec. CI pipeline compute minutes saving around 100min on a single workflow.
But there is even a better news (so be sure to upvote), that knitr may not be required to render Rmd at all in near future.
