I'm trying to use diff-tree --stdin to diff several trees in one
go. But I just get error messages when I feed it two
space-separated trees (one commit works fine):

No, the documentation was made wrong during 1.2.0 timeperiod.

The feature of --stdin to take a commit and its parents on one line was
broken before that to support the common

        rev-list --parents $commits... -- $paths... |
                diff-tree --stdin -v -p

usage pattern by Porcelains.  For diff-tree to talk sensibly about
commits, it needs to see commits, not just trees.

But is there any fundamental reason why it couldn't accept tree-ishes
as well? It only talks about commits if asked to do so with
command-line options.

Or would that break existing users somehow?
