Populate usage section in either nodeinfo or mastodon instance API (or both)

At the moment it is easy to believe that most wildebeest instances are dead because they don't report activity or even basic user numbers (even if there is only one). For example from wildebeest.social:

$VAR1 = {
'version' => '2.1',
'metadata' => {},
'protocols' => [
'activitypub'
],
'openRegistrations' => bless( do{\(my $o = 0)}, 'JSON::PP::Boolean' ),
'software' => {
'name' => 'wildebeest',
'repository' => 'https://github.com/cloudflare/wildebeest',
'version' => '0.0.1'
},
'usage' => {
'users' => {}
},
'services' => {
'inbound' => [],
'outbound' => []
}
};

and

$VAR1 = {
'description' => 'Wildebeest Social',
'title' => 'Wildebeest Social',
'version' => '4.0.2 (compatible; Wildebeest 0.0.1)',
'uri' => 'wildebeest.social',
'email' => 'paul@fastest-hosting-group.co.uk',
'thumbnail' => 'https://imagedelivery.net/NkfPDviynOyTAOI79ar_GQ/b24caf12-5230-48c4-0bf7-2f40063bd400/thumbnail',
'short_description' => 'Wildebeest Social',
'rules' => [],
'registrations' => bless( do{\(my $o = 0)}, 'JSON::PP::Boolean' )
};
