I don't mind doing veros that require larger boxes like the 1590BB, there are a few on the site like the Dr Boogie. This is often the case when the effect has more than 4 pots where most people would want to use a larger box anyway. My only problem is if because of the way I like to do layouts, such as including extra links to keep all axial components lying flat, the layout would end up much bigger than another layout then I don't know what value mine would add to the party.
Some more complex circuits lend themselves better to the layouts Sabro does for instance, because the standing components allow him to keep the final board size down. In these sort of instances I just have a preference to forget vero and use a PCB where most of the time you will get a larger circuit into the smaller box. A good example of this, Matt did a couple of PCBs for me a while ago including an Openhaus, and if I use 9mm pots that would fit quite easily into a 1590B whereas my layout would end up larger than Harald's.
It still isn't something set in stone for me, and if something was requested enough then I'd probably still end up doing it. But I need to motivate myself a lot more to do it
Maybe when I have run down all the other schematics that I have in my to do lists, I'll move on to doing less frequent larger circuits, but I'll let that evolve as time goes on.
