`$JULIA_LOAD_PATH` and Packages with no `Project.toml`

Since I’m using packages dependent on this package, would it be sufficient to do manually create Project.toml for such legacy packages? e.g.

$ cat $JULIA_LOAD_PATH/InternedStrings/Project.toml
name = "InternedStrings"
uuid = "7d512f48-7fb1-5a58-b986-67e6dc259f01"
version = "0.7.0"
authors = ["Julia"]
