I think strictly speaking it's actually BIND_NOW rather than PIE directly
(although in practice the two come as a package):

I think it's a good idea. FWIW, there is another tool that does a similar
thing but using a more supported facility: latrace. This uses the LD_AUDIT
stuff in glibc. If there is desire to have this functionality in main
(something I'm not particularly confident of, to be sure), it would seem to
be a better choice.
