Chrome 30 dropped support[1] for fetching apple-touch-icon-* from well
known URLs, since the 404 pages that are usually returned were consuming
3-4% of all mobile bandwidth usage[2]. We're unlikely to reverse that.

We still support apple-touch-icon-* via link rel under some circumstances
(e.g. for add to homescreen), but they're deprecated[3], since we'd like
authors to use the standard for this, i.e.:

<link rel="shortcut icon" sizes="128x128" href="/favicon.png">

(or even good old:

<link rel="shortcut icon" href="/favicon.ico">

with multiple resolutions in the .ico file for compatibility with IE<11).
