I'm not very knowledgable and I'm sure that a lot of people can answer way better than me but I'm going to give you an example that may apply.
I have to deal with an application API to schedule meetings/trainings. There's no Laravel specific package for it and I have to use an obscure PHP package that's not really mantained anymore even though it's code is good to my eyes (programming to interfaces, kinda close to SOLID etc).
However, the package uses straight CURL and has a lot of lines of code to handle requests, headers etc. If I were to implement it on Laravel I would use Guzzle to give you an example and maybe shorten the amount of code by abstracting the CURL part.
That's what I can think of, I don't know if its helpful or even if it's correct but I guess that Laravel implementations use Laravel native code or its direct dependencies.
Hope it helps
