No, absolutely not.
Whether an observation reached research grade is almost completely irrelevant to its actual ‘value’, and it’s very common for observations of certain classes of life, or from certain parts of the world, to languish for years before getting a community ID.
You can read through he comments of this post, especially as if gets farther down the comment thread to see what the community take is on deleting non-research grade observations as one person there said they do.
