What's the problem?

You use the web but dont think well, world is different out there.
Even world class project like bootstrap doesn't implement it. after 2 major version.
RTL problems 😫
Islamic Calendar ❓
Persian Calendar ❓

Who give sh*t?

Many good project know there are some place in the world use different direction and ui stuff. See more about CLDR and Intl.
CSS until born
Firefox
EcmaScript (JavaScript Intl)

What can we do?

Just consider the i18n stuff like rtl, different type of calendars, number format, currency and etc.
Learn stuff about i18n :D

Best practice?

Explore project like CLDR or many real world class UI project like, firefox, android UI and much more. I think they know much better about i18n.

We need much rewrite, patch, fork as another project?

Yes indeed, because you don't initial your project world class.

CSS sample:
          html {
            // global styles
          }
          html[dir=rtl] {
            // rtl special
          }
          html[dir=ltr] {
            // ltr special
          }
