It should work for sources, but not for layers.
YAML dictionaries are merged together, but lists are overwritten.


```
 sources:
   a: ….
```

and

```
  base: X
  sources:
    b: …
```

becomes

```
  sources:
    a: …
    b: …
```

But


```
 layers:
   - name: a …
```

and

```
  base: X
  layers:
    - name: b …
```

becomes


```
  layers:
    - name: b …
```


Regards,
Oliver
