Hi @richardklose and welcome to the community 
Just to give a quick update on this. This will be part of “Account Management and De-Provisioning” which is on our Roadmap
Depending on your environment and requirements, you might be able to use SCIM instead. SCIM is a standardized way of integrating with IdPs and supports the On/Off-boarding process.
More information about SCIM can be found here
Kind regards,
Daniel
