I would like to add my 2c.

I'm not clear if
there are many other cards that have this same issue.
The list of cards with unprogrammed regdomain can be extended with
several relatively modern models:
* MikroTik R11e-5HacD (QCA9882 based)
* MikroTik R11e-5HacT (QCA9880 based)
* QNAP QWA-AC2600 (QCA9984 based) [1]

As you can see these are powerful and massive cards for WISPs. Or at
least to run as an AP. I also know a bunch of .11a/b/g/n cards with
zero regdomain and the same target audience. Except maybe for the
legacy Wistorn CM9, which is a relatively compact card.

Also, a huge number of wireless routers and access points have
unprogrammed regdomain. But probably this is not the case, since they
anyway can not run a stock kernel.

let me add my 2c. the regdomain 0 is very common and defacto a standard for all non oem cards on the market. i have only seen real programmed cards
as buildin cards in laptops.
beside of these zero cards there are other special regdomains available for ath cards
