Any reviewer writing for a tech site I would hope. Otherwise why do they bother?

differen't sized die sims still an issue (there are different cpu sizes as you note) but with a laser simply changing the distance from the laser would change the focusing area, no?

Not from my experience operating a laser for 14 months. Change the distance changes everything, most importantly heat. Also changes in flatness on the base will cause issues. Lasers are very focus orientated. Doesn't take much to screw it up.
Seen it and already know all about it.

and finally, testing with an IR laser could potentially be better than a die sim because it eliminates mounting variability.

Sure but not by any amount worth the cost. We already have seen die sims have very good repeatability. Plenty good for water block testing. The TIM joint IMO isn't as much of an issue with Die Sims as it is with CPU's.
From what I gather from various threads the CPU TIM joint is the issue being discussed not the joint on die sims.
