The master cylinder is not sealed tight and it doesn't have to be from the standpoint of having a system that stops the car. You can leave off the cap and the brakes will work as they should until the fluid sloshes out and/or the fluid abosrbs enough moisture to make it useless.
You do what makes you comfortable. It seems everyone except the folks who write owner's manuals say to change oil every 3000 miles. You choose who you want to believe.
Are you next going to jump on MB for recommending power steering fluid flushes when few if any other manufacturers or independent mechanics agree? Is it ludicrous to have a power steering fluid filter?
BTW, I hope SteveB doesn't see this thread.
