Because then it would be harder to do this:

  is_deeply( $some_object, { foo => 42, bar => 23 } );

Also, what about this?

  package Foo;
  sub new { return bless { foo => 42 } }

  package Bar;
  @ISA = qw(Foo);

  package main;
  use Test::More tests => 1;

  my $foo = Foo->new;
  my $bar = Bar->new;

  is_deeply( $foo, $bar );

If is_deeply were object-aware should that pass or fail?  Maybe, maybe not.

So I decided to simply ignore the whole problem.  For similar reasons
is_deeply() honors overloading.  If you hand it a string overloaded object
it'll compare it as that string.

In the end, is_deeply() can have only one behavior and is one-size-fits-most.
For more flexibility use Test::Deep.
