Even just providing specifications and some documentation about the devices, someone might write a new driver. Reverse engineering is hard, having something to go off of means they can probably extend support from an existing driver fairly easily.
The biggest issue is probably the MediaTek chipsets. Unlike Qualcomm, they don’t provide the source code.
I only went with MTK based device for manual band selection. It can be done with root, but the only app for it I could find is network signal guru, and I am not sure about how trustworthy it is to give root access to.
