This illustrates an on-going problem with speaking about "Epicureanism" -- how it is understood, what does it represent, what is "Epicureanism" and what isn't "Epicureanism" and who do we consider as "being Epicurean" - these questions will be answered differently depending on whom you ask. And the only way to begin to deal with this is to start labeling all of the common varying interpretations.
Your “no cookie-cutter” comment in another thread is certainly spot on, and I like the approach you’re suggesting here.
As a – likely beyond-the-pale whimsical* – metaphor, perhaps we could think in terms of a philosophical “clade”:
“In biology, a clade (/kleɪd/) (from Ancient Greek κλάδος (kládos) 'branch'), also known as a monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields.
“The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups.”
For example, bees: “Bees are winged insects that form a monophyletic clade Anthophila within the superfamily Apoidea of the order Hymenoptera, with over 20,000 known species in seven recognized families.”
Within that bee clade, are a variety of behavior characteristics: “Some species – including honey bees, bumblebees, and stingless bees – are social insects living in highly hierarchical colonies, while over 90% of bee species – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary.” But all bees (as opposed to, say, wasps) “are herbivores that specifically feed on nectar (nectarivory) and pollen (palynivory), the former primarily as a carbohydrate source for metabolic energy, and the latter primarily for protein and other nutrients for their larvae.”
Recent research suggests that even hive bees – at least bumblebees – also, as individuals, play.

* By way of apology, I might be reacting to this from Emily Austin that I read yesterday: “Our ability to live a good life does not rise or fall with cultural refinement or rarified intellectual skills, and sometimes it’s just more fun to clown around.” It reminded me of something Alan Watts once said to the effect that being sincere is not the same thing as being hyper-serious. As Epicurus said, we must also laugh – even whilst doing philosophy. Then again, the metaphor of a “philosophical clade” might be constructive …
