The proposal is to create a new page to help create dynamics to test new features and enhancements.

This should be well thought out because currently, most of the new features are hardly tested, and they get hard stuck for too long

One good example is this ticket:
https://core.trac.wordpress.org/ticket/31992

Which brings a major enhancement, but there is no clear path for testers who find it too daunting to initiate the testing activities.
