every console library is riddled with games people ought to experience but virtually nobody would proactively seek out, so rather than farming them out to lowest-bidder publishers who will ingloriously dump them onto storefront with no notice and no effort made to engender any sort of affection towards them (or even just to impart rudimentary knowledge about what they are), having them just sorta show up on peoples' hardware and allowing people to collectively and simultaneously stumble upon them all at once allows these forgotten old artefacts to thrive beyond ecosystems that have traditionally boxed them out (ie mass-market anthologies and curated products that lean entirely on hegemonic selections of Essentials)
I'd say this is particularly pertinent to the Game Boy—it was right up there with the NES/Famicom in terms of large portions of the world interfacing with it via multicarts and bootlegs, and thus the lived experience of that system is defined as much, if not moreso, by the likes of Motocross Maniacs and Battle City and That One Doraemon Hack That Says Mario 4 On The Title Screen, and countless other games that are commonly ignored by that one hoary old list of pre-approved classics that's undoubtedly being rehashed by a hundred listicle writers right now, so one would hope there's an audience out there that is hungry to see these libraries represented in their totality, even if it's just for five minutes apiece
