Sicilian bischop trap

I recently played two games in which i could trap the opponents bischop at turn 4. This did however leave me with a very open queenside. My question is whether I should go for it should the opportunity arrise or just neglect the material? Here are the opening moves (I played black):

Yes you should take it :D

Material advantage is well worth the opened queenside. In fact, black can even play Bb7 which will be very powerful if white castles king-side. Note that you don't have to take the bishop right away.

An opened queenside is hardly even a disadvantage if you castle kingside.

Well worth the 2 points.

Of course you should take it; you can just castle kingside with no issues

Nobody has ever played 2.Bb5 against me.

After 2...a6 white can avoid losing the bishop by retreating it, but losing tempo instead.

It is even worse, they mixed the Portuguese with Sicilian.

I searched for 1.e4 c5 2.Bb5 in chess.com database and there are only 2 master games with that.

No name was given by the database to this opening.

 You did not get the hint, perhaps I should be more direct.

I meant, this is Noah Arc trap, which can easily occur in Ruy Lopez if one is careless:
