There is no wrong or right answer to this it’s just what you would prefer
But I do think any Introduction of A character has to start somewhere. And Lando had already been introduced twice mentioned in name. So I personally think it would not be confusing who we were seeing or where it was.
But I do agree the way it is in the film is more mysterious.
I Suppose it’s in keeping with Harrisons fords first shot in the cantina in Star Wars also got scrapped too
