You're missing an adjective from your observation: qualified.
For any given position, even when you're pretty specific on the requirements, you will get an onslaught of applicants who have absolutely no business trying to apply for said position, but they do it anyways just because it vaguely matches a skillset they have and they need a job.
This isn't a criticism of such persons; it's foolish for people to think that a word for word perfect job exists just for them, and kudos to those willing to be a bit flexible on what they previously felt were non-negotiable aspects of jobs (I am referring to things I personally consider trivial, in this case, but I feel that when it comes time to start negotiating, said items are thrown out first as bargaining chips)
We have many employers seeking a specific type of qualified person; we have qualified and unqualified people all looking for jobs; it can be a bit messy to sort the two. This is why the interview process exists.
