CS history has a long history of similar pieces of software being not called compilers.

Normal CS jargon has "assemblers" and "linkers", both of which might appear to be compilers according to this dictionary definition.

CS history also includes things like TeX, which formats text for a variety of outputs, and was rarely called a compiler.

Web browsers often include a JIT compiler for Javascript, but their text formatting system isn't usually called a compiler.
