Fonts being served using the CSS API do not have the same OT features as their downloadable counterparts (fonts.google.com/download?family=FAMILY ZIPs).

If I extract TTFs from the CSS:

/* cyrillic-ext */
@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/rBHvpRWBkgyW99dXT88n7wsYbbCjybiHxArTLjt7FRU.woff2) format('woff2');
  unicode-range: U+0460-052F, U+20B4, U+2DE0-2DFF, U+A640-A69F;
}
/* cyrillic */
@font-face {
  font-family: 'Montserrat';
  font-style: normal;
  font-weight: 400;
  src: local('Montserrat Regular'), local('Montserrat-Regular'), url(https://fonts.gstatic.com/s/montserrat/v12/NX1NravqaXESu9fFv7KuqgsYbbCjybiHxArTLjt7FRU.woff2) format('woff2');

}
/* vietnamese */

}
/* latin */
@font-face {

}

They only contain dnom, frac, liga, numr OT Features. If you download the family from GoogleFonts, they contain a ton more.

I'm guessing our settings for pyftsubset are removing features we deem unnecessary?

Hi, is this in any plans to be corrected?

Today I have to download two whole sets of fonts for using small caps: regular, italics and bold and SC-regular, SC-italics and SC-bold (SC for small-caps, obviously). If smcp font feature was embedded, just one set would be necessary (in this case, three fonts less).
