Complete agreement, but I do have a special case answer to your wonder.
Actually, a special class. Every useful system I'm aware of that stores
information that is rarely read is functionally like the black boxes in
airplanes.
You never want to read it, but you've got to have it, and once in a while
you have to read it.
There is another class that is about 1:1, that being operational data stores
where you capture, cleanse, aggregate and pass on to datamarts, warehouses,
or whatever other buzzword has been recently generated.
But that doesn't rise to your wonder about never retrieved.

Read-mostly, I'd say by 5:1 or greater in most cases.
If you ever saw a system that was write-mostly over the long term, then
there's data going in that's never coming out. You'd have to wonder why
someone would pay money to store things that are never retrieved.

Read-mostly. By far.
