This did not occur to me, thanks for bringing this to my attention! I will definitely look into this! I guess Luminare may end up being fully open-sourced.
Just call it what it is, there are no feel-good points for advertising it as something it isn't.
People are ambivalent about BSL licenses because of the way companies use them to step back from their previous commitment to open source.
They're still an improvement over closed-source licenses.
