This is UN*X, not Windows.  UN*X tends to allow a certain bit of foot-shooting 
to enable people to get useful things done.  It seems that since these 
targets have the same semantics as installworld they should follow the same 
policy.  A user can already blow their feet off in a much worse fashion by 
forgetting TARGET_ARCH when doing an installworld.  The fact that we don't 
have lots of complaints about that particular case now indicates that your 
fears are probably not well-founded.  If someone is doing cross-builds and 
cross-installs, I think we can expect them to be able to set TARGET_ARCH 
correctly for the delete-foo targets since they already have to be setting it 
correctly for buildworld, buildkernel, installworld, and installkernel.
