I think I know the reason they are all going to be Cloud versions instead of actually ported, beyond just 2.8 and 3.
It's going to only be available as a single entity, the All for One collection, that doesn't distinguish them as separate files. 1.5+2.5 probably won't be sold by itself same as 2.8 or 3.
If that is the case and they are considered one download, I haven't checked how All for One functions when bought. Is it a single file size? And would that file size possible exceed the 32 gb that Switch has natively? If so, there's your answer. If not I have no clue.
