Probably the best example I can think of is Diane Duane reworking her Wizards series to make it modern-day, but there are others, including owners of a literary estate altering books left to them to make them compatible with current standards.
What do you think? Does it matter if it’s the original author or an inheritor?
Best examples I can think of are Stephen King’s The Gunslinger and The Stand. His George Lucasing killed the vibe in the Gunslinget to make it look like he had everything planned out ahead of time and the Stand was already too long but now it’s way too f**king long. The best part is how you cant get the originals in any modern edition, hooray
