If you wanna resize a partition, or anything else that essentially rewrites the whole disk... have fun.

I mean yes, but isn't that something quite rare?

At least I never feel the need to do it, the closet I came to something like that was when I switched from a 240 GiB SSD to a 1 TiB one and just mirrored the old disk to the new one with dd, increased the partition and run a resize2fs. While that required ~30 Minutes it was a once in a decade thing for me.
