Irrespective of any mode of blocking you are going to get the crud
that has fallen on the blocking mechanism dropping down when opening
up again, otherwise where do you expect this crud to disappear to?

Even with a bespoke fixed design consider how it is to be cleaned.
I think they centre pivot so the crud slides off when opened.
The fixing trick is knowing that you have to take out and replace
some brick above your fire opening.

No, it would be fixable from inside the chimney and have minimal effect
on the throat when open

Hmm. I have done a couple. Both times the best access was through the
front of the chimney.
