This is a lot less useful way of doing things but it flies almost completely outside the deletionist radar. There is little cultural dance pertaining to the the concept of notability for mentioning something in a list, and no bureaucratic pseudo-procedure for a deletionist to wield against such practice.
Whoa, hold the phone: List of animals in The Simpsons is notable but Nemerle isn't? How does that remotely make sense? The man hours undoubtedly expended in maintaining that list boggle my mind.
But seriously, merging into a list can be a very bad idea when you're dealing with a deletionist. Because 'notability isn't inherited', the list is no more notable than any of its items. Theoretically, you can also claim notability if RSs discuss the list (see http://en.wikipedia.org/wiki/Wikipedia:Notability#Notability... ), but I've never seen this successfully done - what source will discuss 'List of animals in The Simpsons'? How do you show they are discussing your list without engaging in OR? It's basically impossible.
So a list just makes life much easier for the deletionist - one easy target to AfD rather than 20 or 30. (This happened to me recently with [[Neon Genesis Evangelion glossary]]. The nominator would have taken months or years to chew through each entry if they hadn't been merged, with any luck burned out before the end, and I might have been able to save individual articles.)
