Google to add more chaos to Web developers’ lives?

I just saw Google adver­tis­ing their new exper­i­ment ven­tur­ing into the Web browser scene. The Chrome browser, like every­thing else from Google, is in BETA.

Now that is what con­cerns me most: Will this beta soft­ware just adds to foes Web devel­op­ers have to fight when com­bat­ing cross-​browser com­pat­i­bil­i­ties? Does the fact that it is beta imply that it will be con­stantly chang­ing, which mean we’d have to cope with like 10 more dif­fer­ent cases of dif­fer­ent ver­sions of Chrome?
