Storing avatar information into usermeta

[stokim]

Hi there!
I'm looking forward to 6.0, however there are few more things to add.
First, how about storing avatar information into DB, especially filename.
Now, to get avatar url, we have to use functions such as file_exist, readdir, closedir etc.
How about just storing avatar filename generated random id into usermeta?
I found this thread: ​https://buddypress.trac.wordpress.org/ticket/4237
However for 8 years, it has not been changed at all.
I know accessing db is costly, however it would be better to use DB instead of using those functions.
If we can store filename into usermeta, we can use this with attaching -thumb and -full with ease. Thank you.

Only one line can change the way of fetching an avatar URL from directory check to DB inquiry.

$serialized_avatar_url = get_user_meta( $user_id, 'avatar_url', true );
$avatar_url = $serialized_avatar_url ? maybe_unserialize( $serialized_avatar_url ) : null;
You can get both size's url through $avatar_url['thumb'] and $avatar_url['full'];
