Is crossbow expert working on ranged spell attacks rules as intended?

@Eoffram_Troyas @Wizards_DnDJust wondering, is crossbow expert working on ranged spell attacks rules as intended? yes – feat does not specific crossbow or weapon attacks

@GX_Sigma @Eoffram_Troyas @Wizards_DnD Is it intentional that you can use it to get two attacks with 1 hand crossbow + shield? I'd rule it should specify a different weapon, not same weapon twice
