I think an enumerated probe like:
TYPE_SCRIPT_USED,
TYPE_SCRIPT_UNUSED,
TYPE_SHEET_USED,
TYPE_SHEET_UNUSED,
TYPE_FONT_USED,
TYPE_FONT_UNUSED,
etc...

would do.

The "used" notification can be easily made here and here.
The "unused" notification can be easily made here.
The type can be taken from mPreload->mKey.As; needs to be published via a const getter.

DATA COLLECTION REVIEW RESPONSE:

Is there or will there be documentation that describes the schema for the ultimate data set available publicly, complete and accurate?

Yes.

Is there a control mechanism that allows the user to turn the data collection on and off?

Yes. This collection is Telemetry so can be controlled through Firefox's Preferences.

If the request is for permanent data collection, is there someone who will monitor the data over time?

No. This collection will expire Firefox 84.

Using the category system of data types on the Mozilla wiki, what collection type of data do the requested measurements fall under?

Category 1, Technical.

Is the data collection request for default-on or default-off?

Default on for all channels.

Does the instrumentation include the addition of any new identifiers?

No.

Is the data collection covered by the existing Firefox privacy notice?

Yes.

Does there need to be a check-in in the future to determine whether to renew the data?

Yes. :kershaw is responsible for renewing or removing the collection before it expires in Firefox 84.
