Why is the Stacks wallet on Ledger still in developer mode?

I would like to use the Hiro Stacks wallet in combination with my Ledger hardware wallet. However, the Stacks app on Ledger has been in developer mode for more than one year, which makes me feel a little bit nervous. Why it’s still not available like other apps in normal mode, is it safe to use, isn’t there a chance that it will no longer be supported?
