AU fails and strip symbols

I think I ran into a very similar issue today:
I also do the stripping and signing myself in a script that I run after the build, and am now seeing warnings since master 6.1.3:

Is there any way to make the Projucer not set the signing to “Sign to run locally”?

And does anyone indeed know if enabling code stripping in the Projucer has the same effect as doing strip -x -S?
