3.1.4 effectively is a drop-in replacement for a 3.1 ROM.
In situations where you have some libs or similar loaded in the startup-sequence with loadmodule you might get an error. Or maybe if you patch scsi.device of 3.1. Other than that you get instant support for large drives etc.
Doesn't 3.1.4 exclude workbench.library from the ROM? You won't be booting far if you didn't already have that on a hard drive or aren't booting from the 3.1.4 Install disk.
