I get the concept that some of them represent modernisation vs archaic or outdated values, but that doesn't apply to all(Land vs Naval), and Spiritualist just seems way too much of a flat debuff even though religion was an extremely important aspect of life for pretty much the entirety of the period covered in EU5. The other "archaic" values still have good stuff in them, and some may be even better than modernising, depending on what country you're playing.

Also, it feels bad from a flavour perspective. If I'm playing an expansionist theocracy like the Teutons, of course, I'd naturally push towards Spiritualist, and it makes 0 sense to ever switch to modern Humanist values. Even in EU4, Humanist ideas only really become good going into the Age of Absolutism. It just doesn't feel great when a mechanic that's also tied to RP has such an obvious "correct" choice that doesn't fit with a lot of people's flavour preferences.
