I tried already but there are problems with retrocompatibility:

I was also asking if it is possible to remove some hardcoded options
without breaking something but I had no reply.
So this seems to be a response to the first paragraph ("why is this so
complicated, is it fragile").
I'm afraid that I don't think it's really a sufficient response to
"why is this so complicated, is it fragile?". "I don't know" is not
very convincing :-).
My worry would be that these options would change their meaning in the
future, or indeed that the whole edifice which requires callers to
specify things at this excruciating level of detail might (sensibly!)
be abolished.
