Your idea would make it easy to add an unacceptable amount of overhead to GC. Since GC is already the biggest performance killer on the JVM, I don't think it makes sense to give developers this particular loaded gun to shoot themselves in the foot with.

GC is probably the biggest performance killer of most if not all managed languages (i.e. where you can't explicitly free memory).

And Java probably has the best GC algos out there.
