With an M140,
What if it is at 0c? (temp)

the multi-mode 445 diodes start to dim out/die around 2 amps. 1.8 is the accepted max safe current to drive them at
Do we know this to be true of M140s, not just AXXXs ?
No we don't unfortunately.
If there is such data, I would LOVE to see it... I'm sure I'm not the only one.
Also the results from m140's seem to be consistently better than they were with the a140s.
is there a fair chance I Would be able to notice the dimming before it was too late?
Most electroncis can handle more current with cooler temps,
have these diodes been tested at freezing temps?

It does dim out the same. Iam not going to re attempt it as there is a chance of blowing the diode but i can tell you it does the same thing.
Not all do it at the same spot but for the most part it starts ~2050mW +/- 150mA.
@geo, yes, that makes sense. As Cyp said earlier, COD is caused by too much light, not too much current. If your diode is more efficient, it is making more light per given current than other diodes, and will reach the damage threshold of the output facet at a lower current than other diodes.
