Yep.  That is an area that has been identified as needing additional study (see comments by kc, summarized in http://www.icann.org/en/topics/new-gtlds/summary-analysis-root-zone-scaling-impact-21feb11-en.pdf).

I don't know anyone who is pushing to increase the update rate of the root zone.

One of the studies relevant to this was done by DNS-OARC. See http://www.icann.org/en/topics/ssr/root-zone-augementation-analysis-17sep09-en.pdf.  There was an intent to do some follow-on studies, but from ICANN's perspective the interesting scaling questions turned out to be related to the provisioning side, so focus moved away from impact on the root servers.
