As a UK passport holder I’ve certainly noticed more questioning when entering, and leaving, the Schengen zone over the last few years. In Germany and the Benelux countries I’m routinely asked the reason for my journey, duration and have to wait while ‘things’ are checked. I find it quite starkly different to previously.
Spain, France and Italy are far more relaxed and am rarely asked questions.

I don’t know how Swedish immigration works, but in the UK there is no expectation of entry. It is down to the officers on duty to make a decision based on the information provided to them. Discussions of illegality are unlikely to be helpful.
