REST API: How to find groups with “Full Control” permission level using Id and RoleTypeKind

Question

in a javascript file, using Rest API, I need to get groups with full control as permission level.

I call

_api/web/lists/GetByTitle('MyTitle')/items(23)/roleassignments?$expand=roledefinitionbindings

and I've noticed, calling this url on two different sites, that in the returned json the "Full Control" permission level is described in this way:

BasePermissions: Object { High: "2147483647", Low: "4294967295" }
​​​​​Description: "Has full control."
​​​​​Hidden: false
​​​​Id: 1073741829
​​​​​Name: "Full Control"
​​​​​Order: 1
​​​​​RoleTypeKind: 5
​​​​​"odata.editLink": "Web/RoleDefinitions(1073741829)"
​​​"odata.id": "https://pinco.sharepoint.com/teams/pallino/Pallo/_api/Web/RoleDefinitions(1073741829)"
​​​​"odata.type": "SP.RoleDefinition"

. In particulary I've noticed that Id and RoleTypeKind never change in my two sites. I don't have any doubts about RoleTypeKind Enum but I wonder if ​​​​Id 1073741829 is equally valid to find all groups with "Full Control" permission level.

Can anyone help me?

Thanks in advance.
