The UK is still a part of the EU yes. Nothing has changed. Until it leaves the EU. When legislation will change.These are separate issues, though, as the UK is still part of the EU, and therefore has different policies depending on the nationality of the immigrant.
The UK currently has no legislation regarding immigration post-Brexit. Post-Brexit Britain does not yet exist, apart from vague bill promises that lack work-able detail.
The case of EU citizens in the UK is notable due to the fact that they have come to the UK with a full set of rights, which is now under discussion of how much of it is being stripped away.
Also, whatever the UK think their "immigration problem" is, it's not rooted in "insufficient EU treaties".
The significant thing to understand is that people are always under the mercy of the government's legislation. EU citizens won't gain clarity until the regulation gets established and that will still be subject to new governments changing it. It is an issue and one that I can't expect T. May to actually resolve in good faith.
Now, with regards to CSI, that is a direct problem in the EU treaties to account for the NHS. Under the self-sufficiency requirements, you need comprehensive sickness insurance such that you do not burden the state. That makes sense in say Germany where they have social insurance but not in the UK. T. May took advantage of this legal loophole to target EU students and people working part-time. There is active litigation going on but it would be hard to argue now. Having said that being in possession of the EHIC at the time is a decent workaround for this.
