Why was it decided that the unicode encoding argument should be ignored if the first argument is a string? Wouldn't an exception be better rather than give the impression it does something when it doesn't?

From the PEP:

There is no sane meaning that the encoding can have in that
case.  str objects *are* byte arrays and they know nothing about
the encoding of character data they contain.  We need to assume
that the programmer has provided str object that already uses
the desired encoding.

Raising an exception would be a valid option. However, passing the string through unchanged makes the transition from str to bytes easier.
