It can't stop you doing dumb things in code (e.g. use #pragmas or variables in C++ code) which will probably make your build behave funny, because it'll cache outputs not knowing that they're supposed to change. You can of course define these as variables, but that'll just drop all your caches on each build which eliminates the main selling point of Bazel.
