Yes, the new protocol might not be the most pressing part for scaling up
the repository, but I feel like it's the most challenging and fun part for me
when talking about scaling issues. ;)
e.g. if you fetch git.git (and you're up to date!), the git protocol
already eats
130kB of bandwidth, so in case you're on your mobile expensive data plan
you'll hate the inefficiency, it was measured with
git ls-remote git://github.com/gitster/git |wc -c
132048
or as a gerrit developer:
git ls-remote https://gerrit.googlesource.com/gerrit |wc -c
2108657
2MB, That's crazy!

I'm fine with soliciting here on the list for a good cause.
(I was touring Paris yesterday and was near the Eiffel tower and within 15
minutes, there were 4 tries of unsolicited advertising/begging/
[tourist->money conversion scheme])
