Some minor cleanup, looks good overall

[mofojed]

I think you can shorten it, you're not using the keys at all:

Suggested change

	const themePluginEntries = [...pluginMap.entries()].filter(
	(entry): entry is [string, ThemePlugin] => isThemePlugin(entry[1])
	);
	const themePluginEntries = [...pluginMap.values()].filter(isThemePlugin);

[bmingles]

The keys aren't used here, but they do get consumed in the next block when themePluginEntries is iterated, so the key + value needs to be present
