`requireScope` for only select types

[sehilyi]

Is your feature request related to a problem? Please describe.

Is it possible to require a scope(s) for select types and disallow for others? I have the following spec, and we want to force people to use scopes, for example, with feat but not with ci.

          requireScope: true
          disallowScopes: |
            ci
            chore
            docs
            refactor
            test

Should be okay:

feat(scope1): message
ci: message

Shouldn't be okay:

feat: message
ci(core): message

Describe the solution you'd like

When disallowScopes is specified, requireScope should not force to use scopes for given types.

Describe alternatives you've considered

Any workaround would be appreciated.
