Of course, I know the question is not about this specific example. But while things are not changed, some thoughts that might help as a workaround.
@Sarfraz, @balpha just told you they ...
In this specific example, I doubt @balpha
was meant to be a reply to balpha. Hence, I doubt the commenter expected balpha to be notified.
And Sarfraz would have been notified anyhow, as it was his question that was commented on. I also sometimes include the author of the question or answer I comment to (again: this is not required for any notification), just to indicate to whom the comment is addressed. But that does not need the @
-syntax. So, if balpha should have been notified as well, it could have been solved using:
Sarfraz, @balpha just told you they ...
or (ugly):
@balpha, @Sarfraz: balpha just told Sarfraz they ...
