Once again said like someone who has no idea of Apple history...
For example the first Intel Macs were 32bit only Yonah (a step back from some already existing 64b PPC Macs). Then the next generation were 64b Penryn.
There is NEVER a perfect time to make a change, and ANY change you make will obsoleted by a later change. That's life. You can let it paralyze or you can accept it and move on.
Of course M1 will be left in an odd spot.
After A7, 32-bit only A6 was left in an odd spot.
After A11, A10 with its OS-transparent combined large+small core was left in odd spot.
After A12, A11 with what appears to be a 3rd part NPU (Ceva?) as opposed to the different, higher performing Apple-designed NPU, was left in an odd spot.
