You are not reading it right. It is poorly done (it was just cut and pasted to every class and some it fit WAY worse than others), but it doesn’t mean that class reworks are out the window.
“our focus on Hero Talent trees is shifting away from reworks”
They didn’t say “our focus on classes”, but rather Hero Talents.
Basically you are going to get Totemic, Farseer, and Stormbringer. They want feedback on THOSE and not “I hate Totemic, give me something else!”
They have said that next week there is a big rework to Hunters coming, so obviously class reworks (and Hunters are in the same boat as Shaman needing a rework badly) are still on the table.
Now… that being said… this does not mean Shaman WILL get a rework, and that if they do it will come in Beta, or that it will be any good. Given the changes they have made to Warlocks, Mages, Monks, and Death Knights, and the upcoming Hunter changes, believing that Shaman WILL get a rework is likely.
How things shake out, remains to be seen, but their Beta posts (which admittedly SUCKED) are not the end of the world signifiers that people are making them out to be.
