c) Reject the notion that speed is somehow linked to "number of yield
operations", until such time as you actually have proof of that

d) Use "yield from" and declare and/or assume that it is optimized,
which it quite probably will be.

The cost of a yield action is pretty minimal. Don't worry about it.
