Certainly not only interested in commercial use or even "mostly" commercial use, but also not interested in investing much time in something that I now know I couldn't use in any potential employer and would be better off committing to getting comfortable in a more suitable language instead.
When older releases are reaching GPL stage I might well revisit.
I'm a pentester not a developer so my commercial code is not ever shipped code per se, the stuff I do is pretty much all one off hacky scripts to help me out (data manipulation for example) that never see the light of day again and I'd be ashamed to have any real developer or data engineer catch a glimpse of.
I don't usually need this performance, but every now and again my junk code thrown together in a few hours can take a few hours to run and getting that down (and speeding up the many debugging runs) without spending hours/days optimising would be nice.
Nothing I do along them lines would ever take 3/4 years without me being fired, let's put it that way.
Also some network stuff of course but doubt that will see many gains here so not much point there.
Those slow runs are not a deal-breaker - usually runs in the background while I get on with other things.
GPU feature is nice. Had a few instances where password crackers for proprietary software have come up, and I've never used python for those nor have I ever committed to GPU for them, but then again I normally just use whatever the language the reverse engineered code is and flip it around to knock those up too. Assessment windows are short and so spending more than a couple hours on these things is just impossible.
But ultimately nobody would commit to licensing for this kind of software for "that one python guy" when teammates all have different language preferences, and I'd probably only benefit from these performance improvements a couple times a year.
While that might not even count as "production code" under that license I'll prefer to just find a "free as in freedom" alternative.
