Hopefully it won't be long before modders fix this and add in requirements for multiclassing and bring the pre-Tasha's Cauldron stats back.
Why would it need to be modded out?
We can simply choose to put 13s in the classes we are multi-classing into.
Nothing is stopping us from adhering to the D&D rules.
When playing in single-player mode that's true. But when playing in multiplayer, especially with strangers, it is a different beast.
And as I hope for a core rules mod, modding the multiclass requirements and restoring the original stats are part of that.
