SCIM known limitations roadmap

Currently, the IAM Identity Center SCIM implementation supports only a subset of the SCIM specifications (known limitations). Is there any roadmap on providing a full compliant SCIM service? There are several scim libraries which can not be used with AWS SCIM due to these limitations. Desired short term actions:

• groups cannot be specified with createUser request. This blocks a lot of integrations
• add putGroup api
• When adding some standard fields like display when using api, violates the AWS SCIM schema, and requests fail. Thanks
