That doesn't sound right to me. But an upgrade (with same kernel ABI version) *will* temporarily require space for both old and versions of all files in the package. The kernel team has had some discussion about changing linux-image packages to not install vmlinuz directly in /boot: https://lists.debian.org/debian-kernel/2021/11/msg00091.html https://lists.debian.org/debian-kernel/2022/01/msg00236.html https://lists.debian.org/debian-kernel/2022/02/msg00000.html https://lists.debian.org/debian-kernel/2022/02/msg00010.html This would potentially allow for smarter management of the available space in /boot. But I don't think there is any implementation available for this yet.
