What is the "meta" key in WP_Term Object?

I thought it would be term meta but that doesn't seem to be correct.

For illustration I've created a category named "Test" with a slug of "test".

I'm updating its term_meta with:

update_term_meta( 64, 'test_meta', 'asdfasdf' );

This appears in the termmeta table along with other meta keys/values:

get_term(64) returns this:

WP_Term Object
(
    [term_id] => 64
    [name] => Test
    [slug] => test
    [term_group] => 0
    [term_taxonomy_id] => 64
    [taxonomy] => category
    [description] => 
    [parent] => 0
    [count] => 0
    [filter] => raw
    [meta] => Array
        (
        )

)

Why is [meta] empty?

get_term_meta(64) returns as expected:

(
[headline] => Array
    (
        [0] => 
    )

[intro_text] => Array
    (

Looking at the source, that meta property isn't a standard property in the WP_Term object.

However, a plugin/theme can add custom properties to the object using the get_term or get_{taxonomy} filter:

add_filter( 'get_term', function( $term ){
    $term->meta = get_term_meta( $term->term_id ); // all metadata
    return $term;
} );
