That's pretty standard even in newer Sennheisers. I think HD 650 and above you get the big plug. Some might come with two cables, one with a standard plug and one with the bigger.

I have basically worn one of those two pairs of headphones every single day at work since I bought them; I guess I've just had good luck.
HD 559: 6.3 mm plug.
HD 560 S: 6.3 mm plug.
HD 569: 6.3 mm plug + 3.5 mm plug.
HD 579: 6.3 mm plug.
HD 599: 6.3 mm plug + 3.5 mm plug.
HD 600: 6.3 mm plug.
HD 650: 6.3 mm plug.
HD 660 S: 6.3 mm plug + 4.4 mm balanced.
HD 800 S: 6.3 mm plug + 4.4 mm balanced.
HD 820: 6.3 mm plug.
So really the 3.5 mm cables are an exception that are also bundled with Sennheiser's audiophile-tier headphones and absolutely everything has a 6.3 mm plug out of the box.
Never had original 8xx cables to check but I would be surprised if they weren't the same.

I'm not seeing a lot to back up your claims. Especially since a lot of those headphones come with a 6.3 mm to 3.5 mm adapters.
Edit: the 3.5mm male to headphone is Sennheiser 81435 [0] the 6.3mm male to 3.5mm female that fits over it is Sennheiser 562507 [1].

That's actually not true. That plug is commonplace on a lot of music equipment, DJ mixers, etc. that are still manufactured and used commonly today.
I figure there has to be some reason for it in an age when companies are constantly cutting costs.
I doubt many people are trying to drive HD-650's with a phone anyway.
But I believe there's no difference in listening experience. The bigger plug is probably a lot sturdier though. I've had some 3.5 mm jacks bend on me. Can't imagine that on the good ol' 6.3. I have totally busted a 6.3 mm to 3.5 mm adaptor though.
For very long cables or high RF you might want a kind of cable called "balanced", which comes in every size except 3.5mm. Some audiophiles think these make headphones sound better, but it's probably not true.
