The question comes up regularly over the last couple of decades.

The privacy aspect is one part - and could be mitigated by thoughtful  
design of what you would offer screen reader users so it is a client-side  
option like responsive design.

Although like responsive design it can be done or at least tracked  

Some will therefore stay away, some will use it unaware, some will just  
use it.

With regard to the issue of tracking usage, I hope that sort of behaviour  
is covered by a clear, simple to understand, and reasonable privacy  
policy. Have a look at the one from JAWS for something I think is pretty  
good, or the one from Skype for something I think is dreadful (took me  
most of an hour to read, as I recall, and has some real surprises. I trust  
nobody calls their children with Skype, since it violates the terms of use  
which form a legal agreement...).

There is also the issue of whether what you offer is actually good - let  
alone good enough to justify your work and the user trying it out. This is  
complicated, as can be seen by the fact that generally developers get it  
wrong, and worse over time.

There are approaches to accessibility that use information provided by  
users to give a better experience, successfully improving on what  
thoughtful design according to modern standards for universal  
accessibility can do. But it turns out to be much much harder, with many  
potential pitfalls that catch most of the people who try to do it.
