It's just a categorization. It would simply be the defgroup of an
existing application. That way you don't have to invent a new symbol for
every application that wants to use a connection profile and has the
defgroup declared already. For example, 'gnus for Gnus. So in `M-x
customize-group Gnus' you would maybe see an extra button to list and
modify the Gnus-specific connection profiles.

Connection profiles without a defgroup (application) symbol belong to
all applications.

Customize wouldn't be required. It's just an easy way to connect the
profile with other application-specific customizations, but users should
be able to add or modify profiles directly.

Does that make sense?
