Me too.

Yes, like this:

<p>Soviet Union</p>

p::text("Soviet Union") { content:  "Russia"; }  /* result:  Russia  */
html > body p::text("Union") { content:  "Confederacy"; }   /* end  
result still:  Russia  */
/* longest match wins, even with stronger selector weight  */
p::text("Soviet Union") { content:  "SSR"; }  /* result:  SSR  */
/* this rule overrides the first one */

A different case for same HTML part:

p::text("Union") { content:  "Confederacy"; }  /* result:  Soviet  
Confederacy  */
p::text("Soviet Confederacy") { content:  "Russia"; }  /* result  
still:  Soviet Confederacy  */
/* no matching against replacement content  */
p::text("Soviet Union") { content:  "Russia"; }  /* end result still:   
Soviet Confederacy  */
/* rule is too late. "Soviet Union" has already been replaced  */

And with this HTML part:
<p>Soviet <b>Union</b></p>

then p::text("Soviet Union") would NOT match, because it crosses a tag

Or you are using licensed content where you don't get to change the  
HTML, but you do get to provide a style sheet, and you want to change  
some things to match your house style guide ("style guide" refers to  
language standardization in this case, not CSS per se). This kind of  
thing comes up for me all the time. Replacing a CSS file is  
instantaneous almost, but getting text changes is like pulling teeth,  
and takes forever. Even when legal responsibility of what the text  
says is not an issue.

*::text("Log On") { content:  "Sign On"; }
*::text("User Name") { content:  "User ID"; }
*::text("colour") { content:  "color"; }
*::text("biscuit") { content:  "cookie"; }
*::text("home banking") { content:  "online banking"; }
*::text("Calif.") { content:  "CA"; }

I think it could still work well with cascading and inheritance.

Another benefit of the selector approach is that it is more useful  
than to just use it for content replacement. For instance, if I wanted  
my company name to always be bold and red:

*::text("MyCompany") { font-weight: bold; color: red; }

The use cases for that sort of thing are even greater than for all-out  
replacement, IMO.
