that is a good bit of reality-check. are we just just catching up
with somebody else's legacy issues?

well, I used to think that adjustment layers was "just a primitive
and naive way to achieve some kind of non-destructiveness."

so '90s. >^}

but now I see that

- doing a (non-destructive) operation on a layer with a selection
- paint (non-destructive) with a certain mode/tool/plugin (later) on a  
- applying an adjustment layer (non-destructive) with a layer mask

can achieve exactly the same results and each of them is completely
valid, simply depending on what each user finds more logical in
the spur of the moment.

I think applying layer modes to layers with either 'found image'
material or users' own painting is a way of working that can be
the most comfortable for a lot of cases and users. removing it
seems rather impossible.

as I said: only artistic need (not one-upmanship) should be a reason
add one or more layer modes to our arsenal.

maybe there are simply zero arguments to add modes...

meanwhile, can the overlay thing be repaired file-backward-compatible?
