It is called an enumerations of choices, 3 named ones, followed by a generalisation of whatever else might possible as option.
Given that boring languages like Java, C#, OCaml, Haskell are kind behind their times for cool kids to rewrite stuff, that leaves the unamed cool programming language of the month as option, whatever that language may be.
Honestly, you are not making this better. This comment also implicitly puts Rust and Zig in the "unnamed cool programming language of the month" group again unless I completely lost the ability to read English.
And seeing that a writer commented something similar to my comments upthread, I am not very inclined to assume I can't read English.
Still, your point is taken, I just can't help but think I am sensing some slight... shall we call it non-preference... towards a few programming languages.
