It's not necessarily an accurate workaround. Other values will be slightly off, not necessarily just min/max in a channel
eg. limited doesn't work here
RGB 4095,4095,0 => 12bit full YCbCr => RGB 4095,4095,4095
RGB 4095,4095,0 => 12bit limited YCbCr => RGB
4094,4095,4095
You need +2 bits if you want/need accuracy
12bit prores 4444XQ is meant for 10bit sources
