This is annoying from an aesthetic standpoint, but may not matter
except on very limited devices, such as mobile browsers.

I think this might be somewhat covered by the microscape benchmark.


While the results I read are out of date, I wouldn't be surprised to
discover that the following points still hold:

(a)  Total number of requests often matters more than total number of
bytes.  So splitting something into separate includes may be
counterproductive.  (Thus the yahoo UI libraries come pre-bundled.)
(b)  If the page is slow enough that people notice, getting rid of the
text entirely won't save as much as better compression (or
elimination) of images.
