There are no cache instructions…

There are no cache instructions on SVGs on the CDN, could you please add some on?

$ curl -I https://s.w.org/images/core/emoji/2/svg/1f937.svg

X-Cache: HIT
X-Frame-Options: SAMEORIGIN
X-nc: MISS lax 186
Content-Length: 4618

The cache can be set to a long time without causing problems, I’m fine with a month or more.

Also, I’m not sure if it’s possible/desired to compress the data, but I imagine SVGs will compress moderately well.

    Possible to add compression?
    
    Pagespeed complains about compression. Twemoji hosted on Maxcdn doesn’t complain for example.
