This was apparently added 10 years ago to store metadata of UAVCAN components within the PX4 binary. The parameters in the xml are mostly early UAVCAN ESC parameters that are presumably out of date and not used. Also it does not scale to maintain metadata for all the possible UAVCAN components and it causes confusion when users read the metadata documentation because these parameters are not available in PX4. That's why I suggest to remove it.
Improves compression, e.g. current params file: 62KB to 51KB
There's also a PRESET_EXTREME option, which reduces by another 2KB.
We can revisit that once needed, as it increases mem usage as well.
