If the code is smaller and faster, why aren't all ARM programs compiled

Tell me about the downside, I can live with the upside :-)
I'm pretty happy with code-size on the Atmel EB40a, so I'm a bit
averse to changing things.
This posting quotes 20% code size decrease and 50% speed increase.
I have seen ~ %20 code size decrease but also speed decrease.the latter is not as easily
quantified but it was definitely there in tm_basic at least.
