In my opinion, this pattern generally makes sense semantically when used
on immutable objects (e.g., strings in JavaScript).

I don't think this pattern makes sense for mutable objects.  It just
suggests immutability.  And making the canvas context objects immutable
doesn't really make sense without much more significant changes.
