The parameter
separatoris a little too long, usesepinstead.sepis commonly used in the Python world, e.g., instr.splitandpandas.read_csv.sequence_jionwas added in v0.16.0 so it's a breaking change, but I guess very few users will usesequence_join. Theseparatorparameter is marked as deprecated and will be removed in v0.19.0.
