So its more likely a installation error that it doesn't check that the file is newer, before overwriting it.
That's what Joshua @ MSFT thinks too. Hopefully there will be some official word about this on Monday.
I haven't installed SP2 yet, but I have confirmed the browscap.ini file that it comes with is 32KB and only goes up to IE6 and Opera 4. Firefox isn't even mentioned. Neither is Safari. That's how old this file is.
So if you depend on browscap.ini please be sure you backup your existing copy before installing SP2 and then replacing it after the install. That's the semi-official workaround being suggested by my contact at MSFT. He blogged about it but I'm unsure if I can post a link to it.
