I think that would be a reasonable approach (so --enable-kernel affects 
the notes in binaries indicating the required kernel version, and disables 
runtime fallback code, but doesn't stop programs running).  There might be 
a risk of security issues from code that doesn't expect or allow for 
affected interfaces to fail, however.
