Writer was retrofitted to implement Appendable in JDK 5 with the 3-arg
append documented to behave "in exactly the same as ..." the
write(String) method. That's 20 years of subclasses that might be
depending on this behavior. Also 20 years of subclasses that may
depend on the 3-arg append calling the 1-arg append. So my initial
reaction is that the risk may not be low and this proposal will
require significant analysis of Writer implementations before the
compatibility risk can be assessed.

Nobody intends to hastily merge this. I already wrote (multiply) that an
intensive analysis has to be performed and a KI based analysis of
Github WAS already performed.
