Data URLs as redirect URLs

When updating user data, we have the feature to specify a redirect URL address to create a link that will be sent to user's email upon confirmation of the action.
The fact is that I have no desire to create some kind of web page that could simply be used to display a message like "Data change successfully confirmed."
For such a case, I'd simply specify this redirect page, packed as a data URL.
But as far I understand, you don't support this option. Which seems like an omission to me.

Please make it possible to specify data URLs as redirect URLs.
