TMP Font Asset Creator - Quick question

I am updating the Font Asset Creator and would like to know if anyone one is using the Font Style feature highlighted in the image below?

I have not used this feature myself in more than 3 years nor have I heard users reference it either so I am curious if I could remove it.

We’re using TMP for two years and have never used it either

We have used it a couple of times to make some fallback fonts bolder to better visually match the main font.
