Question about Rebirth (No Spoilers)

For context I'm in chapter 3 of FF7 Remake

I've heard a lot about Rebirth being bloated in terms of content. Is this true? I believe you could say that about any RPG I loved FFXV does FF7 Rebirth have the same pacing issues as XV?

Remake feels amazing with the dialogue, characters, and combat is so fun with the little I've done. Does quite a bit change in Rebirth?

Thank you!
