HTML Dialog and name

Hi,

In my workplace we are looking at using the HTML <dialog> in place of the
ARIA role dialog and all its attributes.

I have one broad based question and one targeted.

1. Are there any accessibility concerns for using <dialog> anyone has come
across or is aware of?

2. There is no mention, that I have found in the HTML Living Standard for
the Dialog element, that it needs a name, which is part of the ARIA spec
for role dialog. Should ARIA aria-labelledby or aria-label be used to name
the <dialog>?

If it is best to name the dialog element should this be proposed as a
change in the standard?

Thanks
