For desktop Linux there is Freedesktop.org which is largely still the
established platform to coordinate standards and share some
implementation of standards. However some actors such as GNOME have
become difficult to interact with or ignore some standards. The cost of
that being to improve their platform instead of "Linux", I don't write
GNU/Linux since desktop Linux isn't just GNU but
GNU/Freedesktop/GNOME/Qt/KDE/Linux etc the name would get quite long.

I'm nott using Gnome-Shell but KDE Plasma. For Plasma it works out of
the box once you have the task widget in your panel.
The easiest example for me to test this is a messaging app such as Telegram.
Just have widget add, start Telegram, have unread messages and look.
There are no need to open the options to toggle for you to enable it.
But you can configure the support for those in System-Settings ->
Notifications -> Additional Feedback.
Because usually I don't use a taskbar but a tilling window manager no
taskbar needed, some quick internet searches revealved some information
that might help to understand this.
This post is about KDE Plasma and Qt but the explanation does apply to
any implementation of the support for badges using that protocol:

The official Canonical documentation:
https://wiki.ubuntu.com/Unity/LauncherAPI
This gnome shell extension seems to support the launcher API:
https://github.com/micheleg/dash-to-dock (not-tested)
It's the same extension Ubuntu installs to provide a similar UX as in
Unity 7.
