availableTemplates could potentially be nullish, so we're falling back to an empty object before checking if it's empty. If not nullish, it is always an object.

Have you considered using Object.keys? It creates a smaller array, so intuitively it should be less wasteful 🙂
Instead of the ?? {} suffix I'd consider writing isViewable || ! availableTemplates || ! Object.keys( ... ).length.

nextMeta is always an object as defined a few lines above (L71).

What?
This PR removes the remaining Lodash from the
@wordpress/editorpackage and removes the unused dependency. There were just a few straightforwardisEmpty()usages.Why?
Lodash is known to unnecessarily inflate the bundle size of packages, and in most cases, it can be replaced with native language functionality. See these for more information and rationale:
@wordpress/api-fetchpackage haslodashas a dependency #39495How?
We're using
Object.entries( object ).lengthas an alternative, with a nullish coalescing fallback when necessary.Testing Instructions
_.mapValues()from editor package #49654 and verify they still work.
