For most CPUs the builtin perf JSON event support should make
this redundant.

Perhaps you could list what CPUs it actually supports over
the existing JSON tables.

If it's only a few it would be likely better to add
appropiate json files.

If it's a massive number it might be useful, although
JSON support would be better for those too.
