Not sure if I understand the plan - you want to add telemetry to check if an option which you are actively hiding is the most used?
That would give an unfair advantage to the visible options.
What's bad about sending HTML-only always so that we would need to hide that option?
Users will typically only choose between these 5 options in the prefs *once* in their life, so the number of options really won't matter much.
It's the option with the highest chances of rendering as intended, while avoiding the plaintext overhead.

That would give an unfair advantage to the visible options (self-fulfilling prophecy).
