MTB frame’s are quite a bit more designed this century some of which coming
from the rise of full suspension, but also designing the bike for its
intended use.

 
I don't really care, because we didn't take part in the flight from the
roads to “infrastructure” or forest and gravel paths, which was
propagated from all sides of the spectrum, over the past decades. 
 

That was never a use case for MTB’s particularly or rather bit or a lot
overkill for its use.

This was perhaps a use case for cycle paths. They often hardly differ
from off-road.

MTB shine even XC bikes when it gets much more technical, than just forrest
trails, be that tyres which have grown to 2.4/2.6 from 2.1 suspension and
geometry of the bike which alters the bike and the rider position and
performance, XC bikes have for example had to become more technical as the
races courses became much more technical older MTB endurance races and even
world cub races.

IMO, MTB have brought some valuable innovations, so did gravel bike
frames, even for road use. But both don't shine for road use, even when
combined with occasional and light offroad use.

That's why I combined a gravel bike frame with a Mullet groupset when
building our bikes in early 2023 - road components at the front and a
single MTB rear derailleur.  

In terms of outfit and intended use, it is still essentially a road/race
bike that has been adapted for general road use. The differences are:
Mounting points everywhere, for use with mudguards through to pannier
racks, large clearance for wide tires (>6 cm), a longer wheelbase.
Conversion to an off-road touring bike would be comparatively easy.
Simply fit luggage racks, mudguards and tires with treads. Just an
option for me, I still prefer it like this:

That's almost a road bike frame, combined with a suspension fork.  

People nowadays buy something like this, for a MTB:

There's no question that there are now a number of interesting
transitions. Especially if you build them yourself. :-)

In this respect, we have also stuck with the classic frame shapes,
diamond frames, Mixte or Anglais, without suspension.  I don't need the
slightly lowered top tube at the back, but sometimes I find it quite
practical.
 
Carbon frames are a different story.  I have more experience with metal,
so I stuck with aluminum and then titanium for the frames.
