 Replying to [comment:1 MarcusCalhoun-Lopez]:
 > * Restrict Rust support to x86_64 and arm64 on macOS >= 10.12. The sole
 reasons rust-bootstrap is to support older systems.

 This wouldn't reduce the disk space needed for builds, but could we at
 least reduce the number of builds by setting replaced_by on the platforms
 where each subport isn't needed? So for example rust-bootstrap-10.7 would
 do something like:
 {{{
 if {${os.major} == 9} {
     replaced_by rust-bootstrap-10.5
 } elseif {${os.major} == 10} {
     replaced_by rust-bootstrap-10.6
 } elseif {${os.major} >= 16} {
     replaced_by rust-bootstrap
 }
 }}}
