Well, the ALSA primary goal is to be the complete HAL not hidding the
extra hardware capabilities to applications. So API might look a bit
complicated for the first glance, but the ALSA interface code for simple
applications is not so big, isn't?

Also, note that app developers are not forced to use ALSA directly - there
is a lot of "portable" sound API libraries having an ALSA backend doing
this job quite effectively. We can add a simple (like OSS) API layer
into alsa-lib, but I'm not sure, if it's worth to do it. Perhaps, adding
some support functions for the easy PCM device initialization might be
a good idea.
