I use GPT labels to identify swap partitions, which are not
file systems. GPT labels identify GPT partitions of whatever
type of content. Example from one of my contexts:

# ls -lodT /dev/gpt/*
crw-r-----  1 root operator - 0xd9 Mar 13 01:34:40 2025 /dev/gpt/OptBefi
crw-r-----  1 root operator - 0xda Mar 13 01:34:41 2025 /dev/gpt/OptBswp364
crw-r-----  1 root operator - 0xdb Mar 13 01:34:40 2025 /dev/gpt/OptBzfs
crw-r-----  1 root operator - 0xdc Mar 13 01:34:40 2025 /dev/gpt/HyperVswp4
