If all new operators behave the same as +=, when the variable exists, then
+!= is not needed, because +!= would do the same as +=$(shell ...).

Based on your explanations, it looks like you want the new operators
to differ from +=, when the variable exists.
Which brings me to the conclusion that this is not only about having
+:= create a simple variable, when there is no variable.
This project must have some other goals?
In other words, in which scenarios do you envision the new operators to be used?
