Initialize "Rest Client" with your own HttpClientHandler instance

The "Rest Client" codeunit is fantasic, where the best pratice is to use the Initialize method to use your own "Http Client Handler".

codeunit 50100 MyCodeunit
{
    procedure MyProcedure()
    var
        RestClient: Codeunit "Rest Client";
        MyHttpClientHandler: Codeunit MyHttpClientHandler;
    begin
        RestClient.Initialize(MyHttpClientHandler);
    end;
}

codeunit 50101 MyHttpClientHandler implements "Http Client Handler"
{
    InherentEntitlements = X;
    InherentPermissions = X;

    procedure Send(HttpClient: HttpClient;
                   HttpRequestMessage: Codeunit "Http Request Message";
               var HttpResponseMessage: Codeunit "Http Response Message") Succes: Boolean
    var
        ResponseMessage: HttpResponseMessage;
    begin
        Succes := HttpClient.Send(HttpRequestMessage.GetHttpRequestMessage(), ResponseMessage);
        HttpResponseMessage.SetResponseMessage(ResponseMessage);
    end;
}

This rule can't cover all possible scenario's, but I believe it's sufficiënt when the Codeunit "Rest Client" is an local variable, that the Initialize also need to be called inside that procedure.

If possible I need to check if the variable isn't passed als a parameter to another method (because the Initialize could be done in that other procedure then).

Are there other scenario's I need to take into account here?
