question [blocking]: I'm questioning if these types of changes belong to V7, as V7 is at the end of its lifecycle. My understanding is that V7 receives security and bug fixes, while behavior changes belong to V8 and main (future V9).

Since it is removing the Experimental warning, I am not sure we can consider this a new feature, it is more housekeeping now.

Given that the test was there to ensure that the message was present I do not think these tests make sense anymore.
If you come back to the code and see this test, it is strange 😄

@joaopapereira I did not say anything about a new feature. Removing EXPERIMENTAL from the cli output is a change to the output.

• Negative test assertions removed (including one whole file that contained nothing but).
• Moved the revisions and revision command into the APPS section of the cf help output.

Updated PR to incorporate @Samze's feedback on the main version of this PR:

• cf revision remains in EXPERIMENTAL status.
• cf revisions is no longer in EXPERIMENTAL status.
• cf rollback is no longer in EXPERIMENTAL status.
