Do you mean you'd like to have this behavior by default? One can already use validate=True to have invalid characters cause an exception. I too find it surprising the False is the default, but changing this would be backwards incompatible.

I chose that to avoid mentioning "modulu" or "remainder". I find it straightforward and clear, though admittedly a bit long and clumsy. I don't believe it is inherently misleading, though.
I like your idea of including the number of base64 characters in the error message. I find the phrase "base64 characters" ambiguous, though. I suggest: "Invalid base64-encoded string: number of data characters (13) cannot be 1 more than a multiple of 4"
