Related to this, I see a lot of JUCE based projects that seem nice in principle but if the author has not updated between versions (say using older JUCE6) it becomes difficult to package and argue in their favour.
JUCE breaks their API quite a lot, even between minor versions. So projects that rely on older versions don't have e.g. fixes for high-dpi screen support or linux vst3.
Updating them to new JUCE versions can be quite complex sometimes.
Not good prospective for long-tern support...
