It's kind of a holdover from when server RAM memory was constrained and servers more multi-purposed/less specialized, remembering that EZproxy is not terribly different in 2022 than it was in 2002. To be honest, I'd just set it to a high value like 30000 and not worry much about it. At the Univ of Minnesota we run 3 EZproxy servers with a huge number of stanzas (11k-12k lines of config) and only once every couple of years does one exceed the MaxVirtualHosts 20000 we set, requiring a trip to the maintenance screen to clear them.
