My personal experience tells me that the number of "gzipped HTML" is most
probably higher, since most of the non-gzipped text resources I see are JS
& CSS. Besides, if authors are not gzipping their HTML, DRYing the URLs
will be like putting a band-aid on a major carotid artery trauma. (i.e. not
very helpful, even if it makes you feel like you "did something")

In any case, since URL DRYing does not solve any of the use-cases and
doesn't bring any new functionality, this is a tangent concern that IMO
would be best tackled later on, once we'd have actual data on the usage
patterns, and we'd be able to estimate how important DRYing the URLs really
is. (No need to wait for author complaints, as we can crawl sites and look
for patterns)

If you'd like to further discuss that concern, can you please open up a new
thread? This one discusses solutions to the responsive images problem
use-cases (e.g. src-N, picture, srcset, etc)
