Screw all that! Just run a hose down below the truck, and let it blow to atmosphere like the good olde days!

I have the passenger side JLT catch can that also uses factory connectors and can reversed back to stock in 30 seconds. There is no harm it can do. I has only positive benefits and leaves no "foot print".
I agree with mueckster, not exactly sure how much oil is actually collected in the catch cans on the 5.0 in a 5000 mile period but if its considerable, a catch can is a must. This is the catch can that anyone can purchase for there 5.0 and 5.2 coyote.

My experience with draft tubes in the '50's is in cold weather they would load up with a milky water/oil mix and at temps - freezing they'd ice up as well,not good.I've also seen PCV systems well mucked up too.

Yes, they did. If warm weather, you'd sometimes end up with a spot of oil under the vehicle too.
Ah, the good ol' daze!! No Cats, no PCV system, and leaded 100% gas. We never realized how bad those engines smelled.

Pure poisonous sludge; definitely not good to be dribbling around. If those flows from the crank case are heavy enough to muck up the PCV valve, then the engine must have a lot of blow-by, which is indicating other problems.
The advantage to using a catch can is there, but it's a question of the relative benefit.
The EB engines (and those that use DI fueling only) don't get the benefit of the fuel washing the backside of the valves off, so DI engines can suffer from a fairly bad build-up of carbon/gunk deposits on the valves. Therefore catching the PCV vapors to remove the oil prior to induction is very beneficial.
Traditional FI (such as MPI) does not have this problem, or has it to a much, much lower resolve. The benefit in this regard to using a catch can is far smaller, and would be difficult to quantify.
One can vent to atmosphere easily on a N/A engine. You are violating clean-air standards, though. And, there are benefits to having a "closed" loop system; very little moisture will make it's way inside the engine.
Overall, on a 5.0 Coy, it's generally an unnecessary add-on. Probably a VERY good idea on an EB.
In fact, I believe that the new 3.5L EB in the 2018 engine has a duel-injection system; both DI and MPI. I suspect it was to address this carbon issue at least in part. They obviously figured a way to also get more torque (which they clearly did), and are quietly enjoying the reduced concerns of carbon on the valves as a side-benefit of the multi-discipline fuel-injection approach.

Doesn't take much blowby in northern NY in the winter time to muck up the PCVS.Just the cold to warm to cold temp swings with the attendant condensation will do the job nicely!
I've installed one, a Ford Performance M-6766-A50, on my 2018 5.0 F-150 when it had 100 miles on it. It was supposed to fit the same as a Mustang on the front of the right side cam cover but did not because of the new added port injectors. It can come off in less than 5 minutes and will for all dealer servicing. The longer hose was bought from RockAuto KCV-283 with a little work and a heat gun. I made my own mount for the separator to mount on the battery box. I included 2 photos: before and after
