project-find-regexp is not asynchronous whereas vc-git-grep is.

UI of project-find-regexp is non-standard.  A more familiar UI
would be like in occur, for example, as used by noccur-project.

No problem at all - trying on the Emacs project:

  (multi-isearch-files (project-files (project-current t)))

is like project-search, but with more convenient UI:
it's easier to type C-s to go to the next occurrence than
to invoke the command M-x fileloop-continue that has no keybinding.
