It's not just the userspace interface that worries people, it's also any
board specific quirks that might turn up. A good chunk of the work with
x86 sound support is quirking around platform specifics - look at all
the patches Hans sends for example. In an ideal world this would just
be people worrying too much but the general history with getting generic
code working well on a wide range of x86 hardware it's hard to blame
anyone for being conservative about substantial changes in the software
stack.
