The ARM1156 implements the full Thumb2 instruction set, exactly the same as in v7 except for ThumbEE and features new to v7 in general. > But the updated reason you gave for not allowing V6T2 is that it's > an uncommon architecture (one core, not widely manufactured today) > ... not impossibility. The architecture being uncommon is not in my opinion cause to make life harder than necessary for whomever might some day want to add support for it.
