Spire Font missing Cache TTL

The spire getFont call has a zero cache TTL, even though the rest of the hosted items for spire under /dist (ie, public js file from webpack) has a TTL set. Could you please increase this to at least a couple hours, so that a visitor isn’t repeatedly downloading the same file. While most browsers probably have caching enabled, the TTL is set to NONE on the file. In reality it also probably isn't realistically multi-downloaded for actual users b/c of the SPA nature of the application, but having it show up on GTmetrix and lighthouse constantly as a problem also makes our clients upset. Bots like Google probably are counting it as a problem with core vital calculations. That extra 250+ms hurts, especially when our TTFB numbers are over a second.

This was originally reported on ticket 7936605 as a Bug and I was asked to also report it here.

    Caching Header was added for this in the 5.1.2202 release.

    Do we have an update on this, or is there already a solution for this?
    I'm currently struggling with the same issue.

    Even better yet, Why even have these calls? Allow the font CSS to be inline in the head, will speed up the page load. Would save 4 HTTP requests on the site I'm looking at now.
