is not used by RStudio (making it of limited general interest) but is used by several other front-ends, including the Windows / Mac GUIs, ESS, and Jupyter (via the IRkernel package).
I believe it's also used in CLI. More recently web-based REPLs using webR have also started using this facility for completions. It definitely continues to be relevant and it's nice to be able to rely on a built-in completion mechanism for special setups or environments.
