QDialog: option for blurred background

[ShlomoCode]

Right now when dialog is open there is a grayish background around it.
It would be useful to have an option to choose the background to be blurred effect (to focus the user on the content), something like what is on this site:

You can achieve this using the following CSS:

.q-dialog__backdrop {
  backdrop-filter: blur(10px);
}

but it seems to me that it would be useful to add a boolean prop of blur-backdrop or something similar to enable it for a particular dialog.

Will be available in Quasar v2.14.8.

With some examples in docs:

Is it possible to do that for the Dialog.create({...})?
