This, of course, is rubbish.  People relatively new to the 'net really
have no idea how seriously "bandwidth" was taken in the early days,
and why consuming network resources without good reason was considered
a cardinal sin. 

That's why the If-Modfied-Since header was in HTTP/1.0.

Actually no, which is why it is as optional as If-Modified-Since.  It
also "optimizes" for certain use-cases only (where server-side support
for I-M-S could be cumbersome).  E.g.

You don't help your case by exaggerating.
