What would you suggest instead?

It isn't just about source blocks, see `org-beamer-verbatim-elements'.

At the moment, the only way to pass extra arguments to lstlisting is
using `org-latex-listings-options'. IOW, it isn't possible to set
specific options for a given block.

Though, it should be fairly easy to implement an :extra attribute for
source blocks. E.g.,

  #+attr_latex: :extra key1=val1,key2=val2
