it's not too drastic, but it makes sense to investigate that a bit.

This is not true. What is true is that dc was removed from the list of
mandatory utilities in Posix 2008. It is still standardized.
The reason why it was removed is because it can be implemented with bc,
but the other way around is entirely possible and historical practice.

Toybox is a one-man operation and it shows in the code. I'd rather
recommend busybox to anyone, and I hate busybox!
You as a developer need to decide how you want to write your code. It's
a mistery to me why you presented it here when you are not planning to
even remove some of the insane GNU-extensions.
