Thanks for your answer @jbaty, it’s very helpful.
I’m keeping my TODOs in a small number of separate files and archive tasks regularly: I’m traumatized by the degradation in performance of org-agenda once it has too much data to deal with. It’s not the ideal system (a tad more maintenance overhead than I would like) but manageable using org-capture systematically and the occasional org-id link to more substantial notes.
So for me point 2 would not apply (at least for now). Points 1, 3 and 4 sound like enough to give it a try, though.
Any org-roam-dailies advocates out there?
