I wonder the same thing but it's hard to be able to answer that question. I
can at the very least, though, say that I personally have run into multiple
situations analogous to this back when I was still in OOP land and I did, in
fact, just create mutable and immutable interfaces related by inheritance.
In those cases, a solution like this would have been a bit more concise.
The fact that there is a fairly well known name for this leads me to believe
that it's not incredibly uncommon, but I really don't have any way to back
that up.
