Disable access for a user w/o destroying information a-la "block" ?

The seemingly innocuous "block" of a user is quite destructive.

Blocking user has the following effects:

    User will not be able to login
    User will not be able to access git repositories
    User will be removed from joined projects and groups
    Personal projects will be left
    Owned groups will be left

Is there no way to, perhaps temporarily, disable access for a user w/o trashing his/her membership in things?
