Looks good to me. Although technically the variable "key" should be string|int, because due to the forgiving nature towards non-conforming inputs, you can get tspecials both as keys and values:
MIME.decode_headerfield_params(":=colon;question=?");
(1) Result: ({ /* 1 element */ ([ /* 2 elements */ 58: "colon", "question": 63, ]) })
