According to this Boba Fett is only considered alive cause GL said he survived Sarlacc, but how is that canon if it ain’t portrayed in any media anywhere. Thats the canon that really matters. GL changes his mind all the time so until it’s in media it shouldn’t be considered canon.
All I have to say is “Aftermath”
