tooltip for "Notifications" applet informs about a number of unread notifications

SUMMARY
***
As we've figured out on https://bugs.kde.org/show_bug.cgi?id=460760  proper implementation of "unread notification badges for applications"  is not that straightforward. Apps need to support Unity API ; distros or users should pre-install libunity ; "sandboxed" applications (Flatpak & Snap) need to communicate with libunity on system or pre-package it etc...
So I'm asking for an option which could at least slightly improve user experience in this regard. Currently "Notifications" applet shows a number of unread notifications from history in an information tooltip which reveals on a mouse hover (screenshot attached).
I'd like to see that number on a panel (over, inside, near or instead standard "bell" indicator, whatever design choice KDE VDG would approve). This way increased number could bring user's attention to some missed messages/events. I believe it could be more noticeable than a "shaking" animation (which eventually stops) or a static "bell" icon. Windows 10/11 has this feature so it's probably useful for someone.
