This is by design. The API returns a resource type named person - https://learn.microsoft.com/en-us/graph/api/resources/person?view=graph-rest-beta.

PowerShell requires singularization of subjects/nouns in command names whenever possible - https://learn.microsoft.com/en-us/powershell/scripting/developer/cmdlet/strongly-encouraged-development-guidelines?view=powershell-7.3#use-a-specific-noun-for-a-cmdlet-name-sd01:

To enhance the user experience, the noun that you choose for a cmdlet name should be singular. For example, use the name Get-Process instead of Get-Processes. It is best to follow this rule for all cmdlet names, even when a cmdlet is likely to act upon more than one item.

*/people* APIs have always been singularized to person even in v1.x - https://learn.microsoft.com/en-us/graph/api/user-list-people?view=graph-rest-beta&tabs=powershell#request.

Reopening following an internal discussion with the workload owner. There was an API review exception given to admin/people and the condition at #2202 (comment) does not apply to the API path.
