There's no mechanism to publish a restricted set of sample rates. I'm
not convinced that we should go down that path.
In the case you mention, this isn't applicable if your AU is doing
its work in an offline context (so perhaps providing an offline
effect version would be a good choice in any case). I know in the
past many companies based these decisions on CPU type (plugins were
only supported on G4 with altivec was a popular one) when their DSP
was really pushing the limits.
Its also hard in many cases to really define or quantify "sufficient
CPU power"; this whole notion is not simple to define with current
processor models (particularly with audio usage patterns) and of
course "sufficient" is totally dependent on what else the user is
doing at the same time.
We've also supported a CPU usage/render quality property in our AUs -
the DLS Synth and the reverb for example - that allows the user to
still use the AU but with the ability to limit the computation work
they perform (for instance in the DLS Synth the quality settings will
adjust the level at which a note is considered to be finished).

Hi all,
Is there any mechanism for an AU to report which sample rates it
can and cannot support, or are AUs expected to support any sample
rate if sufficient CPU power is available?
Best regards,
Angus.
