Well, this post of yours has shown me that the problem is more
complicated. Because in this case, it was probably the Right Thing :)
to start a new thread instead of adding this post of yours to the one
discussing category theory and other nonsense.

As long as you reply to the most reasonable post, the flat list still
gets a nice tree structure:
https://srfi-email.schemers.org/srfi-discuss/threads/2020/06/

But it still allows for newcomers to read through all posts sequentially.

(An unfortunate counter-example is what has happened on the SRFI 177
lists: I think it is extremely hard for a newcomer to understand the
timeline of the discussion and, probably, the discussion as well.)
