Unless they changed how the GNAT compiler works in the last few years, then my guess is inertia
to do that.   Right before the pandemic hit, I had the neat idea of doing my own bare metal 
runtime and to use normal uncrunched names.  The RTS compiled just fine doing that.  However,
when I tried to use the RTS to build a full fledged program, it failed to find the package in the RTS.
I don't recall if it failed at compile time or link time, but crunching the names and recompiling the
RTS fixed the issue.  So something in their compiler requires the crunched names, or if they have
since changed that, used to require it.
