Hm, every third release is an LTS: 5.9, 5.12, 5.15, perhaps 6.2.

So, that’s every 1.5 years if we stick to the current release cadence.

As a Qt developer I find this very tempting. But it also means that the whole world has to rebuild all the Qt things every 18 months, which is perhaps not great from an eco-system perspective.
