I disagree.

It's simply not valuable enough to worry about. Especially when there
is a fairly trivial wrapper approach: just make a full-address-space
wrapper than acts as a binary loader (think "specialized ld.so").

Sure, the wrapper may be "fairly trivial" but not necessarily
pleasant: you have to parse ELF sections etc and basically load the
binary by hand. But there are libraries for that, and loading an ELF
executable isn't rocket surgery, it's just possibly tedious.
