This sort of discussion is what leads me to be fond of license disjunctions - perl's use of Artistic|GPL being the one I'm most familiar with. The idea being that "you may use this software under the terms of ${license} or under the terms of the GPL" means there's absolutely no question as to GPL compatibility for the people who value that, and you can pick the value of $license to taste (I use the same license as perl for CPAN releases, but for other languages using whichever is the most popular permissive license you like in that ecosystem is likely a good answer). I note downthread you have reasons why you can't do that with the GPL, and it might be worth having an explanation of that written up somewhere findable given that honestly hadn't occurred to me so I may not be the only one, but I figure disjunctions are still worth mentioning as a general tool even if not applicable in your case.
