I wrote that "(i.e. bare repository)" in 2df5387e (glossary:
describe "worktree", 2022-02-09) but did not mean that way.  

A non-bare repository can reduce the number of its worktrees, but it
cannot go below one, because the directory with working tree files
and the .git/ subdirectory, i.e. its primary worktree, must exist
for it to be a non-bare repository.  Consequently a repository with
zero worktree is by definition a bare repository.

But that does not have to mean all bare repositories can have no
worktrees.
