Further to Lorp's tweet
in which he says "@adamtwar
explains why OpenType features cannot trigger axis position changes" I have a question, which I think is answered therein, but I'd like clarification.
Take the example of small caps. We all know that small caps glyphs can be accessed in a font as an OpenType feature, by way of the `smcp` table. I've also seen an example
of small caps built using an axis (Noboto Flex). Could the small caps be 'built' using an axis and accessed as an OpenType feature?
As a web designer, I ask because it feels to me that there would be a file size saving, especially if the technique is extended to other alternates such as numerals. But also OpenType features is the right way to access these glyphs, particularly on the web where you might need to fall back to system fonts if a webfont doesn't load for example.
