Clearly, `org-element-parse-buffer' is not adequate for the task. When
buildings the agenda view, you're most probably interested in very
specific parts of the document, whereas Element tries to be as thorough
as possible.

I suggest even to not use any org-element-* function there.

I don't want to sound offending, but your 400 locs library cannot
possibly be "very similar" to 10k locs org-agenda.el. Also, after
a cursory look, it is not clear how you solve the multi-days issue.
I.e., AFAIU, you still run multiple checks on the same entry.

Nevertheless, I think your approach is right. I think that, at some
point, we'll need to rewrite "org-agenda.el" from scratch, like we did
for "org-export.el" a few years back, so it becomes manageable again. In
the process, we definitely need to find a better replacement for
`org-agenda-skip', as done in your library.

So, in a nutshell, I think you're doing a step in the right direction.
I hope Org can ultimately benefit from a better "org-agenda.el".

My 2 cents,
