2H as a weak two in either major. It’s devastating. The WBF outlawed it because it was impossible to play against.

It's a Brown Sticker convention and subject to restrictions on when pairs can play it. I don't see anything in the WBF system regulations that outlaws it though, unless they are arguing the requirement that "a viable suggested defence to any Brown Sticker convention must be filed" is impossible to meet.
WBF Systems Policy said:
2.3 Brown Sticker Conventions and Treatments
The following conventions or treatments are categorised as ‘Brown Sticker’:
a. Any opening bid of two clubs through three spades that:
i. could be made on 9 high card points or less AND
ii. does not promise at least four cards in a known suit.
[...]
EXCEPTION: a two level opening bid in a minor showing a weak two in either major, whether with
or without the option of strong hand types containing 16 high card points or more, or with
equivalent values. Defensive measures are permitted for opponents as in 6 below
So Multi 2
♦ is an exception to being a Brown Sticker. There is no exception for a Multi 2
♥ opening (called 'Major Flash' by Chris Ryall) as long as the bid can be made with 9 hcp or less.

what I’m currently playing: 2S 10-13 hcp.
The policy seems to allow 2
♥ as Multi with 10-13 hcp instead of Weak Two strength.
