I’m sorry but I don’t get what you mean.

I know the intricacies of the Microspline freehub and that there is an adaptor. I just wonder if we needed another cassette interface at all when there are two already available that’ll space up to 12 cogs and one of them has been around since 1996.
Did people make this complaint when SRAM went 11-speed? If so, the answer is the same.
It is not. SRAM went 11 on Shimano’s HG carrier until they needed to put a 10 T cog that didn’t fit. The only alternative was the Capreo HG freehub design which is not very good for a MTB. So they designed one from scratch. I don’t know the “people” but it sounds like a good reason to do it to me.

Shimano could have used the XD freehub carrier. But they chose to make their own instead.

Shimano should make SRAM compatible hubs?

It is what it is, want a 10t cog, you're gonna have to dump that freehub that has been around for whoever knows how long...or spend 50% more (XT vs GX) for a SRAM cassette.

My point is that SRAM does the same thing for MTB, and there's silence. Then they do it for road....again, silence. Seems like something we should be used to.

Shimano does not make an XD (Sram Xd could be said to be an "evolution" of Capreo, or at least part of the same idea) why sometimes (not always) think better things

When you launch Dura-ace 12s, I doubt I will take out a Microspline-R (Sram XD for Mtb, XDr for road, or Sram didn't think so ??? ) as I put before, the Microspline could be compatible with HG cassettes and who knows, and who knows if Shimano or other brands will make HG 12s (11-XX) cassettes if they take out the patent adapter

ps: I hope it is understood, my English is limited and I help myself with translators.........

If you are are worried about durability i wouldnt go with 12 speed, just 11 speed with a larger casette

Yes. Or Sram 11, with smaller front (32?). Much less weight. 100 grams on cassette alone.

shimano shifts so much nicer than sram under load, and can pedal backwards in the big gear without the chain falling off! havent had xt long to comment on reliability, but I went through 3 gx rear derailleurs in maybe 18 months, the cages are made of cheese. The freehub is a pain but luckily i was on dt hubs.
