Execute Stored Procedure - Procedure Name without schema

I am using Execute Stored Procedure smart service plugin where its documentation says - for a Procedure Name input, "If the procedure belongs to a package, the schema must be present with the package (E.g APPIAN.BOOKPKG.SP_LISTBOOKS.". But I am able to call it without schema name too (like BOOKPKG.SP_LISTBOOKS). Are there any disadvantages of using it this way? Because my schema name is environment specific and I don't want to take overhead of dealing with it.
