As far as I understand, it was both for the simplivity and interoperability.
Besides, MAC does not add much in termd og security.

> Sorry if this has been covered before, but am I missing why MAC or some
other OAuth2-bound token can't be used in OpenID Connect? Is it for the sake
of simplicity ("just pick one") or interoperability ("... and stick with
it"), or is something else strongly binding to the Bearer spec?

> I think it does. OAuth allows access_token to be used in HTTP header, GET
param, and POST param (body), and the text goes "Access tokens sent in the
authorization header must be Bearer tokens<
If the client is using the HTTP GET method, it SHOULD send the access token
in the authorization header." so it is saying:

Bearer tokens scheme.

i.e., Body.)

read OAuth.2.0.Bearer?

does not call out the use of the body as an option for the access token,
since access tokens can get large there may be issues using only the header,
the bearer token specification allows usage of the body, so should the
openid standard specification.
