Is the config value laravel debug_hide or debug_blacklist undocumented on purpose?

[Rowlando13]

Laravel version 8. The config variable for debug_hide / debug_blacklist disappeared from the docs in laravel 7? Is that an oversight or was that intentional such as it may be removed. Both still work for me.

lararvel 7 docs
laravel 5 docs

Those should have been defaults in the core to not expose envs on debug. Someone proposed that and got ignored.
Both do the same thing
foreach (config('app.debug_blacklist', config('app.debug_hide', [])) as $key => $secrets) {

a more efficient way would had been

foreach ((config('app.debug_blacklist') ?? config('app.debug_hide', [])) as $key => $secrets) {

Why? Devops like to deploy public repos with debug on for some reason.

Update.

Someone said in here somewhere that if TO does not like something, he removes it from the docs.
