Re: [whatwg/xhr] Abandon hope of removing sync XHR from the web platform? (#20)

So I'll chime in here with the standard response that I always tend to leave whenever I see articles and issues on the Net having to do with removing some already standardized feature based on 'metrics' or 'instrumentation' and watching pages fly by on the public Internet. Google has done this for a while and now Microsoft has taken up the practice as well.

At first blush, this sounds like a great idea. The problem is that almost everyone involved is looking at the public Web (probably because they work at companies that only do public Web work). The problem is that there are literally millions of web pages behind corporate/organizational firewalls that no search engine will ever see - ever. I work very closely with developers of internal corporate web applications whose app will never see the light of day outside of their org.

These developers use features that the W3C or the originator of the technology told them were standardized long ago. The effort to rework these applications to accommodate *removal* of these features are staggering in terms of both time and money. Sync XHR is one of those features.

My opinion, which I've expressed elsewhere, is that the Web needs to a purely additive platform, at least in terms of technologies that have been standardized by either the W3C, WHAT.org or (in a few cases before these organizations existing or had the force behind them) an ad-hoc standard.

Putting a deprecation warning might make folks here feel better, but it isn't really going to change the reality of all of those Web apps that no one can ever 'see' that contain code written long ago by developers that have long since left the project that *will* break when changes like this are implemented.
