Some shield is better than no shield, and the proper sized shield is best. There is debris coming up from the roadway - that is the issue. Keeping as much foreign matter off of your brakes as possible should be more than just a minor concern.
Down to just a blue car now.

Am I wrong or do most new cars with disc brakes NOT have shields?
No you're right (at least I think). New cars don't have them. Personally I think that the spinning rims block all debris from the outside and there's not much chance of something popping up from the inside. I figure if there are millions of new cars running without them, then why can't the classics?

No I don't think they are that important on a collectible car that presumably doesn't get driven off road. None of my motorcycles have them BTW. Dave

If you what to run the early shields with late rotors you need to modify them slightly.... The stepped area around the grease seal needs to be removed, it interferes with the larger bearing area of the late style rotor...

Found this out the hard way after struggling and wondering why the rotor wouldn't seat, dooh!

"Are brake shields important?" IMO, No. Ask this same question in race or corners forum, and they will likely ask which rock you crawled out from. As for as debris, I can't say I see much debris collect on the inner surface of a rim, and that surface doesn't have the self cleaning effect of centrifugal force of say a 60 mph spinning rotor. Regarding water splash, seldom is a rotor that hot, and if it is, there is seldom much water around, and if you have ever dropped water on recently hot welded part, the water, instantly vaporizes, carries little heat in the steam bubbles, but not sure what effect water has on friction on a cold rotor, but it still can't remain for long on a spinning rotor. Factory installed them imo likely because of lawyers, I say dump them both
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

What do they do? Keep balljoint grease off the rotors?
Thanks.
Since you referred to the Mopar Action brake swap, I'll take it a step further... According to Mr E-berg, one of the reasons that Ma Mopar used the shields was to keep heat that radiated from the rotors AWAY from the tie rod ends! I omit the shields on my cars though. I havent stressed the brakes enough to get the rotors THAT hot!

But motorcycles can't experience a sudden brake-difference between the left and right front tires if water just lands on one of the rotors. There's also no tire 'on the otherside' which can splash water onto the opposite brake-rotor.
On the other hand, these 'dustshields' also have open slots near the center where they mount. It wouldn't surprise me if such a shield is there to aid in brake-rotor cooling somewhat by directing airflow onto/around the rotor better. Although that leaves to wonder why a shield is only just on 1 side of the rotor and not both.

I daily drove my 5th Avenue in Seattle (kinda wet) for a year and a half with no brake shields. Never a problem.
