When encountering an object element IE7 seems to block all embedding by
default and it issues "security warnings" [1] . Afaics that virtually
drives the final nail in the <object> coffin [2].

That makes tutorials that haven't taken this into account outdated, and
since UAs are not going to drop their existing support for the element I
don't see why this should be an issue with regard to deprecation.

[1] IE7 "Information bar" displayed when it encounters an object element
(embedding a PNG image): "To help protect your security, Internet
Explorer has restricted this webpage from running scripts or ActiveX
controls that could access your computer. Click here for more options."

A further "Security Warning" dialog is produced if a user were to
consider allowing it: "! Allowing active content such as script and
ActiveX controls can be useful, but active content might also harm your
computer. Are you sure you want to let this file run active content? Yes
/ No"

[2] "Virtually" since there are some cases where by using conditional
comments authors can still use the advantages of the object element
whilst feeding IE an <img> element instead.
