Select field with relationship, does it need validation?

Forms\Components\Select::make('profile_branch_id')
    ->relationship('branch', 'branch_number', function (Builder $query) {
        $query->where('profile_id', $this->ownerRecord->getKey());
    })
    ->exists('profile_branches', 'id', function (Exists $rule) {
        $rule->where('profile_id', $this->ownerRecord->getKey());
    }),

Forms\Components\Select::make('profile_branch_id')
    ->relationship('branch', 'branch_number', function (Builder $query) {
        $query->where('profile_id', $this->ownerRecord->getKey());
    })
    ->exists('profile_branches', 'id', function (Exists $rule) {
        $rule->where('profile_id', $this->ownerRecord->getKey());
    }),

When creating a select field with relationship options do i need to validate that the selected option is actually in the list of available options or does the component check this already?

I think not vendor/filament/forms/src/Components/Select.php:930 ```php...

I think not vendor/filament/forms/src/Components/Select.php:930

`php
return Rule::exists(
    $relationship->getModel()::class,
    $component->getQualifiedRelatedKeyNameForRelationship($relationship),
);

I forgot to mention that in my case i have to check if the branch belongs to a profile, so i do have to keep the check.
