And there was no intel xorg driver release for a few years...

That's because we stopped building vendor-specific userspace display drivers and instead work on a cross-vendor shared KMS driver.

What's misleading is that intel xorg driver is still actively developed (or mabe just maintained) in git, bugs are handled, fixes are commited. The difference between it and other drivers is that no releases are made.

Few people were asking here and there (me included on irc) on what's going on but never saw any answer or clear indication that intel xorg driver is obsolete.

No idea why it is maintained if (big if) it is obsolete and modesetting replaces it.

Intel's DDX driver is still an alternative to the standard infrastructure for 2D acceleration in Xorg but not Wayland. It's only the 2D acceleration and isn't relevant to OpenGL / Vulkan. It also isn't really relevant for programs implementing hardware accelerated rendering via OpenGL like Chromium.

The modesetting driver obsoletes it — for any GPU that can be called an actual GPU. I've got several i915/i945 devices that still need the intel driver and its SNA code. The one time I got modesetting+glamor to actually run on those without X crashing at startup, the desktop was unusable.

There's no 2D equivalent of the DRM/Mesa stack, so the dark ages of Xorg drivers poking the hardware (semi-)directly will probably live on indefinitely.

For me with the modesetting driver with skylake based hd-5300 seems to work just fine. Only played one day, but also the Vulkan seems to be supported out of the box on Mageia. (No even need to add
option "DRI" "3"
line to xorg.conf, that was needed with the other Intel 915 driver.
