What will happen when the default is undefined or empty?

It says:

Apart from that, when no default is provided, it should still show the meta key.

I'll test it.

Registering a field without default value:

is returning the meta key:

It seems that is returning an empty string, as documented here:

If single is false in register_meta() args. get_meta_data_default() should return an empty array.

When testing, it returned undefined. But still is showing just the key. I should review if we are covering all the cases with tests.
