I've created a new global config variable in my extension,
....
"config": {
"OresModels": [
"damaging",
"goodfaith",
"reverted",
"wp10"
],It doesn't seem to be possible to override that global from LocalSettings.php, because the array value I attempt to override with is array_merge'd into the default array.
Maybe this isn't a bug, I haven't RFM for this yet.

I recommend that people use assoc arrays with boolean values like:
{ "config": { "setting": { "Foo": true, "Bar": true, "Baz": true } } }
So removing a value can be done by setting it to false.
With list arrays, it's impossible to figure out whether the configuration says $wgFoo = array( 'bar' ); or $wgFoo[] = 'bar', since the defaults are applied *after* LocalSettings.php is read, so for now it assumes the latter.

Fix when no merge strategy is used
We have this problem as well at the permanentfuturelab.wiki , especially with the Visual Editor extension in combination with the foreground skin. Our Wiki hoster Miraheze tried to fix this with the provided patch, but this brought a new problem, the Visual Editor didn't show well in the vector theme (some buttons disappeared).
Discussed again in T142663, the preferred solution is not not use flat arrays, but assoc ones instead.
