As with a lot of things, I’m sure it all depends on the scope of the change. Personally, if I ‘own’ the original bbappend, then I consider if it’s worth establishing an override or some other similar mechanism within that bbappend, depending on what I’m developing (an image feature or something machine-specific). If it’s a one-off for a specific build that I can lump together with other changes, then I go with a new layer specific those changes.
One thing to keep in mind is that if you create your own layer with a bbappend ,then layer priority will impact which portions of your bbappend overwrite the others and the original recipe. You can use bitbake -e package-name to get a view of how bitbake is overlaying all changes for it.
