You mean the argument name?  Fine with renaming that - PROJECT-DIR or
DIR are all ok (DIR is used in ‘project-switch-project’ just above the
added function, so maybe that’s best).

Even though the argument is a directory, I chose the function name
‘project-switch-project-by-name’ to stay close to projectile, which uses
‘projectile-switch-project-by-name’ for the analogous function.
