So why didn't the Beis Halevi write like that? Or Netziv? (Reb Itzel Ponivitzer though did write kabala notes all over Nefesh Hachaim.) They was 60 years later, no?
They were from two and three generations later than him.
You're right, there had been a change in what was common among the rabbinic elite in Lita during that time period.
My best guess is that misnagdus contributed to the change.
