I can say with 100% confidence that third-party, non-cracked launchers are not broken by this migration. I run Lunar Launcher, which is not a cracked launcher, and doesn't allow you to play with a cracked account (Unless you get a cracked version of their launcher illegitimately), and never ever ever requires you to punch in your login credentials. It latched to my main client, and since I was logged in on that, I was good to go. A similar method should be able to be implemented here. And this big concern about turning your client into a "Cracked Client" doesn't make sense, not only given how Lunar Launcher works, but also given the fact that your launcher has already been cracked, and can be accessed by cracked accounts that way. And this is very, very publicly known. Essentially you're forcing legit players to use a cracked version of your service just to play with these modpacks.
