Do you want us to specialize or not?

Not really.
I find that very dull. I love omnicrafting and being able to be resourceful enough to make what I want. That was part of the appeal of the Job wheel in the first place.
Much as the Red scripts seem to limit us now, there looks like there's still good use from cross class skills, and general basic materials.

The only real point I can see from these limits is to slow down our endgame capabilities for some reason.

It's kind of the equivalent of raid design where you're mostly time locked to gear up one Job at a time, but you can eventually get all to the same level.
I think that's the level of specialization they're promoting. You may give each crafting class a level of priority and order but there's not hard limitations to stop you from gearing all eventually.

Unlike the battle classes, though, it still favors omnicrafting due to how connected the cross classes are.
Cross Class with Jobs is much more accessible due to it being limited to only 2 other classes.
