And everything hinges on what one finds "reasonable".

As discussed in bug#51167, in the wake of electric-indent-mode being
honored in Org 9.4, plenty of people have come to emacs-orgmode to
express that they did not expect RET to indent.  Thus Org maintainers
chose to change the default value of org-adapt-indentation for Org 9.5.

Note that by default (electric-indent-mode t, org-adapt-indentation nil)
RET *does* indent in some specific scenarios, e.g. "- list item RET"
will indent (resp. with electric-indent-mode nil, "- list item C-j"),
because Org assumes that you want to add a paragraph to your list item.

To recap:

- electric-indent-mode is enabled by default in Org, as it is globally
  in Emacs: hence RET indents, C-j does not.

- org-adapt-indentation tells Org whether you want your documents to be
  hard-indented or not: starting with 9.5, they won't be by default.

That does look like a bug, however.
