Na, nothing "catastrophic" will happen, or else you won't be able to
development your app using development configuration...HOWEVER...the
performance of your app is likely to double when running in deployment
mode, some exceptions won't be visible to the user (i think
component-in-use-check and others), serialization checks won't slow
you down, that kind of stuff.
If you look at the WebApplication class, you will find lots of getters
like getRequestSettings(), getApplicationSettings() and so forth, from
what I know, development configuration is a defined set of these
configs which sorely focus on helping you while developing, but they
won't help you at all while running in production mode, cos they're
not optimized for that. On the other hand, deployment configuration is
a defined set of these configs which sorely help you getting
performance and "be in production".
It's like running your app with logging on trace level when in
development...If your app is any good, it may be it won't harm you at
all (we had an app out in production running in development mode for
weeks), but your performance will suffer for sure.
