Distinguish between configs and logs/debugs/statistics within sysfs (/sys)

Use case is to build a profiling tool which can identify the runtime configurations of a system. Could it be that read-only files correspond to logs/debugs/statistics/information and read-write files are tunable parameters always? For example: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor is relevant for profiling as it indicates the value of CPU frequency scaling governor and is modifiable. However, /sys/devices/system/cpu/cpu0/topology/core_cpus is just the internal kernel map of CPUs within the same core and is unmodifiable.
