So far ZL have a pretty good record of actually making and selling "planned" lights (with the exception of the "2xAA side-by-side" light, but I don't think they ever claimed it got past the "thinking about it" stage to the "yes we are going to make and sell these" stage.
I believe more choice is usually better - a bit like the ZL UI gives you lots of choices of output (but is easy to quickly get the one you want).
For the people who don't like thermal management there are choices/compromises to be made (by both manufacturers and buyers). Smaller lighter lights simply don't have the capacity to dissipate a lot of heat, so most reputable manufacturers are conservative and reduce max light output ALL the time, or they allow a higher initial output but reduce when it gets too hot to save the emitter (thermal management).
Other choices are: allow the emitter to be degraded due to excessive heat; significantly increase the size and weight of the light to allow better heat disssipation.
As buyers, we can weigh up all factors before buying a light.
