I want to add a `[workspace]` to the monorepo [`Plots`](https://github.com/JuliaPlots/Plots.jl), mostly because of [`Dependabot`](https://discourse.julialang.org/t/psa-github-dependabot-now-supports-julia/134997).

How should I structure it ?

Will a toplevel `Project.toml` **without** a name, uuid and version work ?

**Project.toml**

```toml
[workspace]
projects = ["RecipesBase", "PlotThemes", "RecipesPipeline", "PlotsBase", "Plots", "GraphRecipes", "StatsPlots"]

```

If I add a placeholder such as :

```toml
name = "PlotsWorkspace"
uuid = "8e1d987f-9c8e-4191-8ed6-a4aafebe3192"
version = "1"

```

I end up with things errors like that :  
`Error: Missing source file for Base.PkgId(Base.UUID("8e1d987f-9c8e-4191-8ed6-a4aafebe3192"), "PlotsWorkspace"`.

Should I only add a default `name = "PlotsWorkspace"` ?

If it doesn’t I’d say it’s either a bug or a misfeature.

If you have both name and uuid, the environment is assumed to define a package.

I suppose you could but I doubt it adds much value.

FWIW, I routinely use a toplevel Project with workspaces but no name / UUID / version to manage sets of PRs that span a set of different packages. Which is essentially the same thing as a monorepo.
