The only real concern here are applications linked against libx264,
which someone might want to run on low-end hardware, because I don't
think anyone would want to encode anything to H.264 on non-SSE2 capable
CPU (i.e. Pentium 3 or Athlon XP and older). Considering last non-SSE2
CPUs went out of production about 8 years ago, I think it's fairly safe
to assume that the impact of doing SSE2-only builds would be negligible,
if any.
