Custom Connector as a Portable Library of Functions

Currently, a custom connector requires a Data Source and a Authentication record associated to a function in order to be Published or exposed in the 'Get Data' dialog/window.
This is perfectly fine for data sources, but if I want to create a custom connector that creates data using native M functions, like. List.Generate or List.Dates, then I shouldn't have to define a Data Source nor an Authentication which complicates things and is an unnecessary step for the end user.

Here are 2 videos showcasing 2 functions that do not need any sort of authentication, but due to the way custom connectors currently need to be constructed, they get prompted for credentials as an "Anonymous" user:

The idea: to remove the need for a DataSource/Authentication record for custom connectors that act as library of functions so they can be published on the 'Get Data' dialog and not only shared as environment variables.
