It's not about restricting the language. It's that practising programmers often don't know a subject well enough, so they use different words to make distinctions that don't matter as much as they think (see "transpile"). "Dynamically typed" is actually not that big of an offence (because the distinction is real, it's just that the terminology is a bit muddled), and the people in PL theory who are bothered by this (most notably one person) are considered pedants even among their colleagues.

E.g. many practising programmers don't know that tracing moving collectors are used to avoid some of the high overheads associated with memory allocators (malloc/free), which are themselves big and complex beasts that make up substantial "runtimes" (another misused and misleading word).
