Not necessarily a hassle. My 2012 Volvo truck did require a new DEF doser valve at around 400k miles. It was a very quick diagnosis and fix and while I couldn't tell you the exact cost at the moment, it wasn't anything jaw dropping. My '16 Cascadia (Detroit DD13 engine) is nearing 450k miles and trouble free so far. Of course there is the expense of getting the DPF cleaned, but I had that done while doing a bunch of other maintenance so it wasn't an extra delay. Maybe I just jinxed myself, but so far...so good.
In all fairness, OTR trucks have very mature and robust DEF/SCR/DPF systems and have good success with them for hundreds of thousands of miles. The same cannot be said for their light truck equivalents and there are plenty of tales about the problems they have--form every manufacturer along with the $$$ that inevitably go along with it.
With that said, having to contend with whatever issues arise with those systems are part of what one has signed on to when purchasing a post-2007 light diesel and it is irresponsible to "gut" or bypass the emissions systems. I never had any visual or olfactory indications that my 2015 Powerstoke was a diesel, in fact, one had to listen closely to detect it was and from that perspective, it was quite enjoyable. The "knowing I will eventually have a major repair bill" department was not something I relished looking forward to, so I sold it when I sold my fifth wheel. YMMV!
