Is it okay to inject a default HttpClient from .NET Core's IHttpClientFactory into GraphServiceClient's constructor for HttpClient reuse?

I'm using the Microsoft.Graph SDK in my ASP.NET Core project, and want to take advantage of .NET Core's HttpClient management via IHttpClientFactory.

I see that GraphServiceClient accepts a HttpClient parameter in its constructor, allowing me to pass in an injected HttpClient directly. It seems to be working fine.

But I did notice the constructor's documentation says:

The System.Net.Http.HttpClient to use for making requests to Microsoft Graph. Use the Microsoft.Graph.GraphClientFactory to get a pre-configured HttpClient that is optimized for use with the Microsoft Graph service API

The typed HttpClient instance I'm injecting in is the default one created by .NET Core's IHttpClientFactory. Does it need some extra configuration to be "optimized" for use with the Graph SDK?

The HttpClient created by GraphClientFactory has BaseAddress set to

https://graph.microsoft.com/v1.0/

With the following DefaultRequestHeaders

SdkVersion: xxx
FeatureFlag: xxx
Cache-Control: no-store, no-cache

MaxResponseContentBufferSize is set to 2147483647 and Timeout is set to 00:01:40.

It should not be complicated to set up HttpClient for Graph API manually.
