Functionality deprecations with APIv1 removal

Dear Engineers,

With the API v1.0 deprecation, there are some functionalities which are not available under APIv2 as it can be seen here: https://developer.atlassian.com/cloud/bitbucket/deprecation-notice-v1-apis/#a-name-deprecated-v1-api-a-deprecated-apis-and-2-0-alternatives

Is there any possibility to keep the following functionalities with APIv2?

GET /1.0/groups/<accountname>/
POST /1.0/groups/<accountname>/
PUT /1.0/groups/<accountname>/

{group_name}/members/{user_name}
DELETE /1.0/groups/<accountname>/{group_name}

/members/

{user_name}

Thank you for your help,
Norbert
