Yes. For example it may say that other browser vendors care about things other than x86/x86-64 and ARM (which are all Chrome cares about; it doesn't run on any other architectures).
Of course if you _want_ use of the Web to be tied to particular hardware architectures, then Chrome's push with NaCl is ok. But some people and organizations consider such ties to be a really bad idea.
