I think there are several use cases for a Nyquist fade tool, which is why this is a hard choice to make.
If you want to know what VI users would like it would be best to post on the Audacity4Blind mailing list ( FreeLists / Audacity® recording software and how the Blind can use it ). I’m a moderator on that list but I am not sure what they want. I suspect they just give up on complex manipulation of amplitude within tracks.
Feature Requests has lots of votes by implication for customised fades and/or text envelope.
New controls for start and end amplitude - quick linear fade to target volume from say 0.8 to 0.2, much simpler and quicker than the Envelope Tool (and VI-accessible) (25 votes)
- Additional Choices of dB or % gain, and linear or logarithmic (8 votes)
- Should include multiple envelope points (4 votes)
Probably the 25 votes overestimates the demand for the dreaded fading to a target because that idea was bundled into the description, but you can assume at least 15 people like the target fade idea in principle.
If you extrapolate into the equation the known criticisms of Envelope Tool as being “too fiddly” (some of which criticisms are I am sure not addressable in a GUI envelope because it would dumb it down too much), then I think there is a strong case for text envelope. If it is not ready to be shipped with Audacity, then of course it should not be shipped. What is wrong with it as it stands now?
