Hello,

ada-mode depends on uniquify-files, which ends with this:

> ;;;###autoload
> (setq-default project-read-file-name-function #'uniq-file-read)

This unconditionally changes the prompt for project-find-file at
startup.  I think this is a bit of an overreach: users who install
ada-mode are not necessarily looking for a new project-find-file prompt
for *all* their projects, including those unrelated to Ada.

I'm attaching

- a patch for uniquify-files to remove the above snippet, and add a bit
  of commentary explaining how to opt in to uniq-file-read,

- a patch for ada-mode to explicitly let-bind
  project-read-file-name-function before calling project-find-file,

- two more patches for ada-mode, which I didn't squash with the first
  one because I'm not 100% sure they are desirable: one to make
  ada-find-file support future Emacs versions; another to use
  ada-find-file in ada-mode-menu.

Let me know if this needs more work; thanks for your time.
