OAuth Flow: Token URL from Settings

7.3.4. OAuth Flow: Requesting an Access Token

Rather than hard coding the token path to /v2/oauth/access_token the token
acquisition URL could be another URL made available via the settings URLs.

Is it really necessary to redefine the parameters of the token API endpoint?
Could this not be deferred to OAuth2?

The point here was to profile OAuth2 to have a narrow always working set of functionality. Likely this needs a second look into.
