Interesting. Okay, well that sounds like a great idea for a plugin then. Props for coming up with it.
It is still active. The post I linked to may have been published in 2015 but that was an announcement for a guideline still present today. Read starting under this headline: 17. Respect trademarks and projects.
The "other people did it so I can too" isn't an excuse I've seen work very often when it comes to WordPress.org rules. I would recommend following the trademark guidelines (which could get you in trouble with WooCommerce itself, not just WordPress.org) even though it appears you've gotten away with it for now.
Just not worth it IMO.
