TC39-TG2 would like to see completion of the TG5 study

[sffc]

There has been an issue open for a few months about starting a study in TC39-TG5 focused on what shape of Intl.MessageFormat would be most helpful for developers on the Web platform. tc39/tg5#3

We discussed this today in the TC39-TG2 meeting, and we agreed to the following recommendation for the members of the MessageFormat Working Group.

TG39-TG2 requires that a TG5 study be complete before moving forward on the Intl.MessageFormat proposal. The study's scope should determine what shape of Intl.MessageFormat API and syntax delivers the most value to Web developers.

Because Intl.MessageFormat depends on Unicode MessageFormat 2.0, TC39-TG2 recommends that the TG5 study be completed and feedback from the study integrated into Unicode MessageFormat 2.0 before that specification graduates from tech preview.

Additional notes: here and here.
