Yes, I've used it and the behaviour that we saw was it reporting every issue that had been in the repo ever (including in files that had been deleted). Which I suppose you might want, but every other scanning tool I've used chose the sensible default of scan what is there now.

Also, as far as I can, the security centre wouldn't let you download a .csv of current security issues in the repo - the UI lets you do a bunch of filtering, but the .csv always gives you everything, including issues that you've closed.
