Quotes and commas - wght: 100/400/900 | wdth: 25/100/151 | slnt: 0 | GRAD: 0 | opsz: 14

* comma - In 400 the comma is not as long as it is in 900 & 100 ( and in wdth: 25/100/151) and so it doesn't have the contrast with the curly or smart quotes that I see in the other weights @ opsz: 14.

This is a case of the David & Santiago fixing what was wrong in 400 in the rest of the design space. I think they should be given permission to fix it in wdth: 100 wght and 14 opsz too even if that makes it not match roboto perfectly. It would be clearer then and higher quality.
