> The reasonable thing to do would've been to differentiate refugees from others
This is exactly what we are doing, but this requires actual checks, not just a look at a person's face.
I was working in a Starbucks in North London and sat next to a businessman. He started advising his wife/fiancee's distant family members on the phone who had travelled to Greece.
He gave them detailed instructions to (1) destroy their passports and forms of ID, (2) claim to be Syrian refugees fleeing from a war-zone and spend a couple of days rehearsing their stories.
He also gave them useful advice about the pros and cons of different country's refugee processing systems.
There are obviously many migrants genuinely fleeing war-zones (and it is understandable that many others wish to escape oppression/ poor economic situations) but self reported origins + reasons should be taken with a pinch of salt. Many applicants know that claiming to be from war-torn Syria guarantees a successful asylum application due to the Geneva Convention, whilst admitting being an Afghan economic migrant complicates things.
If you are referring to refugees who enter through those two countries, you are ignoring that these countries are also not initial ports of entry into the Schengen Area.
But I generally refuse to follow that line of argumentation: Having the initial ports of entry bear the responsibility for all new refugees is only a fair thing when you are not one of them. Neither Greece nor Italy have the capacity and as long as we are playing hardball international politics in the countries refugees come from, we have to take responsibility for the results of our actions.

Now, suppose you are a refugee, a mechanical engineer fluent in Arabic and professionally competent in English.
Would you have a preference for a country like Sweden or Germany where you are more likely to get a job with your skills? Or would you equally accept being told to move to some other "safe country" where there is high unemployment, little demand for mechanical engineering jobs, and few English speakers?
How do you express that preference without your refugee status being questioned?

In that news article, Timmermans also argued that border closures are not the right solution.
Edit: If https://euobserver.com/migration/132048 is correct, then the 40% refers to the people specifically from Syria. Most of the remaining 60% are from Iraq or Afghanistan. As that link says:
> almost 90 percent the people who arrived by sea in the EU in December came from countries gripped by war or emerged from a wider regional conflict.
I furthermore have a severe problem with categorically saying that Moroccans "have no reason whatsoever to ask for refugee status" - the country is not as bad as it once was, but political activists are still far from safe [2].
