Thanks for the clarification. Indeed https://en.m.wikipedia.org/wiki/MIT_License#Ambiguity_and_variants explains that FSF didn't like the name MIT and recommends Expat instead. However, MIT is currently the most popular open source license in the world and everyone else uses it by that name, including 'usql' itself, so I will also use that name.
Would it be possible to activate the 'spdx' mode via the config file so it doesn't need to be passed manually?
