I'd prefer a function :: WorkspaceId -> Layouts rather than a Map. A Map
will always leave you with possible runtime failure cases. A function
might be incomplete, but that's not as bad (in my opinion).
Serialization here is an interesting problem.
One option would be to create a container type that can contain various
types of layouts, something like a variant of Choose which can have one of
its layouts disabled. This would allow us to avoid having any changes in
the serialization code, and would also work nicely with dynamic changes of
layout options (removing or adding options from a given layout). I have no
idea how it can be made palatable in the config file... but I've got to go
