I don't understand this. There shouldn't be any 'packages' directories anywhere
in a checkout of any dart-lang repository, so it seems pointless, and probably
wasteful to mark them as being excluded. (I believe that IntelliJ currently
sends all of the exclusions to server, which then has to check each of them
every time it walks the directory structure and every time a file is added.)

If you have 'packages' directories on your system, please remove them, then
consider removing these exclusions from the metadata.

This is the IntelliJ metadata file - these excludes are part of what it ignores,
not the analysis server.

From talking with Alex, this file can get much simpler as soon as the lowest
supported version of the SDK is one that no longer supports 'packages' symlinks.

But to reiterate, these exclusions are not related to the analysis server, or to
any packages symlinks on disk.
