all: false always disables all plugins

As per the docs you can send events to a single destination with the following properties when sending the event:

analytics.track('eventName', additionEventProps, {
  plugins: {
    // disable this specific track call for all plugins except customerio
    all: false,
    customerio: true
  }
})

This would disable all plugins except customerio and therefore the data would be sent onto to customerio.

A common use case for plugins is to enrich data or do something else that is not related to sending data to a provider (e.g. filtering events).

However, the use of all: false also disables any enricher-only plugins you might be using meaning that you need to have event configuration like:

analytics.track('eventName', additionEventProps, {
  plugins: {
    // disable this specific track call for all plugins except customerio
    all: false,
    customEnricher: true,
    customerio: true
  }
})

This can be quite error-prone as its not immediately obvious that all: false will have side effects of turning off enrichers and means that developers need to always be mindful of re-enabling any custom plugins following an all: false.

It would be great if there was an option for a plugin to be able to ignore the all: false flag and always be enabled in this scenario.

Something like:

export default function customEnricherPlugin(userConfig) {
  return {
    name: 'custom-enricher',
    alwaysEnabled: true, // <- something like this or ignoreAll: true
    config: {
      whatEver: userConfig.whatEver,
      elseYouNeed: userConfig.elseYouNeed
    },
    initialize: ({ config }) => {
      // ...
    },
    track: ({ payload }) => {
      // ...
    },
    ...
  }
}

No files or tests are named. Start by tracing how per-call plugin configuration handles the all flag and plugin definitions, then determine how an always-enabled enricher should interact with provider selection. Done means an opt-in plugin can remain enabled when all: false is used, while the documented customerio-only behavior still works.
