Cons
Con Introduces breaking changes between major versions.
Ok, it's beta software, I guess, though it is 2-3 years old? Still less than v1.0.0. But still, they introduce breaking changes in a patch or minor level bump? Not even documented, discussed, or acknowledged in bug reports.
Con Not well documented.
There is some documentation. But the current capabilities are not well documented. Common use cases are not explained. The documentation is self-contradictory. Changes to code functionality not reflected in documentation.
Con Runs on the JVM
JVM is a double-edged sword (startup time, memory usage, CPU overhead, ...) which might be considered overkill for a static site generator.
