Yes it is I think. If people are using versions of IE that old, then
they deserve to have an older version of the "web" given to them. There
are plenty of browsers available for even the older operating systems
(Chrome, Opera, Firefox) so not having a new one available is no excuse.

Why is adding attributes smoother? User agents still have to be modified
to 'understand' an attribute to make the same semantic sense as a new
tag, so you gain nothing. You're just swapping one flavour for another.

If you're using an older version of IE then likely it's because you
don't know any different, and also likely that you don't even know what
Javascript is, let alone know how to disable it. I can't back this up
with facts, just personal experience.

Attributes can be semantic, but where do you draw the line? From what
you're saying, all tags in HTML could be reconciled into one and you can
just use attributes to differentiate:

<tag type="image" src="blah.png">
<tag type="para">text</tag>
<tag type="italic">text</tag>
<tag type="css">.blue{color:#00f;}</tag>

Would you really favour using attributes to determing the meaning of a
tag, or would you rather that HTML just follows its natural course and
attributes be used to supplement a tag from default values?
