The fact that as new features are added, the paths still become

I mean what while nobody can remember SHA-1 identifier, you can also
either write it down, or get is from output of some command, and then
copy-paste to other commands that need it.

Likewise, since bjam prints the full path to the target it creates,
you can copy-paste the path if you want to run the binary, or look
at some other target.
