Actually it's a bit more work to do, there had to be different profiles for every resolution and probably material.
What you as a user would see is actually a check box only. But I would add to, that this option is overdue for years now (others also).
Maybe they have no trust in their own printers capabilities or just like to earn some more $ from selling more filament (all those wasted filament for the raft).
I have such decent raftless prints on a printer with less accuracy than the M200, just by replacing its PEI bed with an alu plate an Builtak surface.
On my M200 I replaced the perfboard months ago by Buildtak wich gave me even better adhesion and removal of prints together with less filament dust and no scratching of prints off the perfboard.
People have managed to remove the raft with bits of software, and it doesn't always work.
Small parts usually come out ok, but warping on larger parts without the raft can really gunk up your machine. There may be other solutions to this (like buildtak) but you dont stand a cats chance in hell of Zortrax ever adding the option to remove raft.
