*ahem* That's SI = Systeme Internationale.

Named SI for two important reasons:
1. No one else uses it
2. They're French

If so, there are many SIs, because:

The International System of Units (SI,
abbreviated from the French Système
international (d'unités)) is the modern
form of the metric system, and is the most
widely used system of measurement. [1]

OK, list a few current bikes with 35mm threaded BB, 22.0mm
stem or 25x1 headsets please.
Then root around your bike shop for 5mm bolts threaded 0.9
SI rather than the dominant DIN 0.8.
While you're there, look for current production 14mm pedals.

My Stronglight 93 came with British threads, or the first owner British-ized it, or I did and just forgot. I don't remember wrestling with the pedals.. It was the first bike I stripped and rebuilt. I learned that the OE headset had ten-thousand tiny loose balls in it -- which ended up all over the basement floor. Every time I tried to upgrade something, I was thwarted by an odd-ball French standard. I grew out of the bike and later gave it to my girlfriend who rode it across the US. Yes, the bike Eddy Merckx rode to victory in the TdF could be fitted with racks, fenders and a TA triple for a cross-country ride. It also had my home-built Mod 58/PW hub wheels on it that were bomb-proof. I think these days it would qualify as a fast gravel bike.
