As a side comment: "another primitive isn't needed" is kind of a
fundamental LaTeX mantra: as opposed to LuaTeX/Context, traditional
LaTeX development has always taken the position of being "downstream",
making do with whatever the engines (with a particularly long and
thorough focus on the original TeX engine) provide.
