[Mailman-Developers] Is it possible to use Postorius alongside the legacy interface?

Hello,

I wonder if it's possible for users to choose between the new Postorius interface and the old text-based interface? Some users might prefer the text-based interface (e.g., for accessibility or just familiarity); others may prefer the new interface (which does look quite snazzy!). But, I didn't find any documentation about switching between the two.
