Intent to remove: emergency services dialling (911, 112, 000, &c.)

Almost no one ever uses it: metrics show only around 0.02% of phone calls use this feature. So we’re planning on deprecating and then removing it.

Just an idea that occurred to me earlier today. XSLT doesn’t get a lot of use, but there are still various systems, important systems, that depend upon it. Links to feeds definitely want it, but it’s not just those sorts of things.

Percentages only tell part of the story. Some are tiny features that are used everywhere, others are huge features that are used in fewer places. Some features can be removed or changed with little harm—frankly, quite a few CSS things that they have declined to address on the grounds of usage fall into this category, where a few things would be slightly damaged, but nothing would be broken by it. Other features completely destroy workflows if you change or remove them—and XSLT is definitely one of these.
