Adding your own personalized controls to the toolbox

While this post is a bit old, - https://social.msdn.microsoft.com/Forums/en-US/5a4409b8-1b4f-4240-b79a-4619e2185a64/using-the-new-xamarinforms-controls-toolbox?forum=xamaringeneral - In Xamarin adding personalized controls to the toolbox was not possible.

Right now we don't support adding your own personalized controls to the toolbox. As far as sharing the control itself, custom controls are their own class, so they can be in their own XAML file which can then be shared.

Is that fixed in MAUI?

Is this the possible solution (it says it is UWP only) - https://docs.microsoft.com/en-us/nuget/guides/create-ui-controls?
