"N" is preferred default.

In most cases that's true, but for WLAN_VENDOR_ configs 'default y'
should be used. It's the same as with NET_VENDOR_.

I would like to challenge it, why is that?
Why do I need to set "N", every time new vendor upstreams its code?

You don't. The WLAN_VENDOR_* settings are not supposed to affect the
build, just the Kconfig visibility.

Which is important to me, I'm keeping .config as minimal as possible
to simplify comparison between various builds.

IIRC the 'default y' is to avoid breaking when updating from an old,
pre-vendor, kernel config (for example with 'make oldconfig'), otherwise
all wireless drivers would have been disabled without a warning. But as
wireless vendors were introduced back in 2015 in v4.5-rc1 I don't think
we need to worry about that anymore. But I would like to keep this
behaviour consistent across all vendors, so they all should be changed
at the same time in one patch.
