Sanctum SPA: set api guard driver to 'sanctum'?

[plai2010]

I am using Sanctum for a first-party SPA. The documentation ("Protecting Routes") suggests configuring the API routes with middleware('auth:sanctum'). I try instead changing the 'api' auth guard driver to 'sanctum' (in config/auth.php):

'guards' => [
    ...
    'api' => [
        'driver' => 'sanctum',  // instead of 'token'
        'provider' => 'users',
        'hash' => false,
    ],
],

The allows me to use the usual middleware('auth:api') for my routes. It seems to work, but I wonder if there may be issue with this approach.
