This problem is solved by a good chess timer. I saw this papal game with a timer of 4000+400 on full WT ;)

Nothing like that. Well, they will play not for 2 months, but for 3 on a good timer. The essence does not change. In WT, at least you can gain control, but in SOD you may not, and then the game in the format of "moshna vs control" can drag on indefinitely. The fact that they played XL in Novosibirsk is my fault, but I was once again convinced that XL+U is bad for tournaments, and every tournament confirms this. Maybe try 8mm6a for L+U?

ps. WT will not be the default version of the game in any form. by mutual agreement - maybe.

I do not recommend WT even by agreement. WT in its current form is a breeding ground for bugs, desynchronization, gray castles, etc. In Novosibirsk, a lot of time was spent on curing a gray castle. And the CIS-2013 also confirms this thesis.
