Nope, just like Import-Package does not support split
packages.

We do not remember not found packages.  The reason
is new packages
could have been installed.  We could remember
and then flush the not
found packages if new bundles are resolved.  We
have not done too
much optimization here because in general we do not
recommend using
dynamic imports.

Yes we cache found package sources just like normal
packages that 
come from Import-Package or Require-Bundle.

This cache is flushed when the bundle is refreshed
or the platform
is restarted.

I caution against using Dynamic-ImportPackage unless
there is absolutely
no other way of doing things.  In any case I
would never recommend having
Dynamic-ImportPackage: *

That will only give you unpredictable results because
you will have no
idea of where all of your packages come from.  You
should
scope the dynamic imports down to the package without
wildcards if
possible.
