Various discussions convinced me that `org-adapt-indentation' should be nil by default.
With `electric-indent-mode' being activated by default in Emacs, the current behavior is that RET after a headline moves the point below the beginning of this headline, not the beginning of the line, which might surprise users. Indentation is quite sensitive: what do you think of setting a new default value of nil for `org-adapt-indentation' in Org 9.5? -- Bastien
