But do you agree that with your current proposal, you still have to fix all
scripts that use -e/escape codes?

I would agree with you on this point for anything but echo. I don't think
this reasoning applies here given what's in the Operands section and what
the rationale is. It seems to be clear to me that the intention was to not
allow any options, i.e., to make sure that all implementations of echo echo
all of its arguments unless the first operand was -n.
