By adding addition friction, one reduces that 'accessibility'. Adding unnecessary friction by doing extra work setting something up as feed-only so that readers have to do extra work to decide if the feed-only content is worthwhile, the question I have is 'why?'

Subscribing to a site sight unseen, no pun intended, is not something I or anyone who is protective of their feed inbox would do. I curate my feeds so that I can sit down a few times a week and deeply read.
