Last time when I looked OpenWRT was unable to support MIMO and beamforming capabilities of many of the devices it was running on.

This capabilities are crucial to have decent coverage, signal strength and throughput where I live (i.e.: crowded/congested wireless networks in an apartment complex).

Did OpenWRT team managed to work around them, or did the manufacturers started to play nicer with open drivers with loadable firmware?

Some routers specifically allow openWRT.. example, Routers like the GL.iNet GL-MT6000 (Flint 2) and TP-Link Archer AX6000 come with OpenWrt pre-installed and are designed for easy OpenWrt use.

...usually because they have a fork of the codebase, and it's not vanilla base OpenWRT.
