Can this become a thing?

I am aware that this would make fuzzier the rule of tags having to be unique, but I've found myself and others using this format and only discovering why something so seemingly straightforward does not work -- until the reference is digested properly (which can be misunderstood as far as locate()'s flexibility).

Just wondering if this is something that can be implemented without too much rearranging and/or breaking of things.

Thanks for reading.
