Please look back at the earlier discussion we had on this exact point:

Heikki, perhaps now you understand my continued opposition to your ideas
for simplification: I had already thought of them and was forced to rule
them out, not through my own choice. Tom, note that I listen to what you
say and try to write code that meets those requirements.

as possible to "do the job", whatever we agree that to be.
