I bought in to the oil separator hype when Ford moved the fuel injectors, and quickly set about to see how bad the valves are in my 2015, and found they didn't look any different than any other vehicles I've owned... at 100k miles. I was told there would be cylinder-starving levels of build up on the valves, but that isn't the case with my engine. I'll continue to monitor them, but it sounds like whatever issue some people have had, appears largely restricted to the early years of HPFS, and may not be due solely to the ingestion of crankcase vapors.
One thing I'm thinking is the amount of blow-by is steadily reducing as piston and cylinder tolerances get tighter and surface durability is improved.
Weekly? How much do you drive? I empty mine every 5K and it's not even half full.
A catch can is cheap and if it helps any little bit and doesn't hurt at all, why not?
Accumulation will vary by engine, environment, can design, and can placement. I've seen reports of a few days to a full year to fill cans.
As far as hurting... I doubt it but... do the oil vapors help seal the valve seats? Do they provide some lubrication? I've always stopped short of having valve work done on my engines. Haven't had time to go down that rabbit hole, so I've only picked up on fringe conversations.
The stuff these catch cans accumulate smells disgusting. Kind of like gas that's been sitting in an old steel dirt bike tank for 10 years and completely skunked.
Might have to try and light it on fire in the gravel next time. Sure smells flammable. 700 miles, about a 1/4 full. Not a very big canister, might hold 8 oz total. Drivers side can was empty.

what engine? you should send it to Blackstone labs to get analyzed to see whats in it
2.7L , It's been raining pretty much non-stop for about a month straight here in the PNW so humidity is 100% all the time. Condensation is always a problem this time of year.
Willing to bet it will not fill up so fast or look so bad once it dries out. I'll keep an eye on it.

Depending on where you are within your preventative maintenance schedule, consider doing an oil change or a quick drain/plug and replace what was lost, in order to get an oil sample to send for analysis...see what your fuel dilution is...
